#SOLVE FOR X PROBLEMS AND ANSWERS HOW TO#

Multiply each fraction in the equation by the LCD.Then subtract the same number, you are back where you The LCD of 5 and 3 is 15, therefore multiply both (3x + 4)/5 = (2x – 3)/3

Apply division or multiplication property to make the coefficient of a variable equal to 1.

Simplify both sides of an equation by applying simple algebraic operations.

Determine the lowest common multiple of the denominators (LCD) of all fractions in an equation and multiply by all fractions in the equation.

In solving equations with fractions, the following steps are followed: This method is also called the “ clearing of fractions.” To solve equations with fractions, you need to transform them into an equation without fractions. If you know all the rules for adding, subtracting, multiplying, and dividing, it’s a piece of cake for you.

X= -2 How to Solve Equations with Fractions?ĭo not get panic when you see fractions in an algebraic equation. Solve for x in the equation -3x – 32 = -2(5 – 4x)Īpply the distributive property to remove the parentheses.Īdding both sides of the equation by 3x gives, –4x + 4 – 4 –2x = 2x + 16 – 4 –2x –6x = 12 x = –2Ĭheck the answer by plugging the solution into the equation. Use the distributive property to remove brackets 2x – 6x + 4 = 2x – 4 + 20 – 4x + 4 = 2x + 16 The like terms are then combined and then the variable isolated.

Solving equations using the distributive property entails multiplying a number with the expression within the parentheses. X = 4 How to solve algebraic equations using the distributive property? To solve this equation, divide both sides by the coefficient of the variable. To solve linear equations by division, both sides of the equation are divided by the variable’s coefficient. X = – 45 Solving linear equations with division Multiply both sides by -1 to make the coefficient of the variable positive. Multiply both sides of the equation by the denominator of the fraction,

Once you notice a variable being divided, you can use multiplication to solve the equations. Linear equations are solved by multiplication if division is used in writing the equation. 20 = x Solving linear equations with multiplication Subtract both of the sides of the equation by the constant 30. Subtract 2x from both sides of the equation. Subtract 4x from each side of the equation. Solving equations with variables on both sides by subtracting Now add 14 to both sides of the equation. The solution is of this equation is, therefore,Ĭheck whether the solution is correct by plugging the answer into the original equation. And 12.ĭividing both sides by the coefficient is simply dividing all through by the number attached to the variable. Simplify the equation by combining the like terms. The constant attached to the variable is added on both sides. The equation now has only one variable on one side.Īdd the constant 12 to both sides of the equation. Simplify the equation by collecting the like terms on both sides of the equation. Since an equation has two sides, you need to perform the same operation on both sides.Īdd the variable x to both sides of the equation Y = 11 Solving equations with variables on both sides by adding Subtract 26 from both sides of the equation 15 -26 = 26 – 26 -y – 11 = -y Subtract 7 from both sides of the equation. Add 3 to both sides of the equationĬheck for the solution by substituting the answer into the original equation. Here, the variable is on the RHS of the equation. Let’s see a few examples below to understand this concept.Īdd 7 to both sides of the equation. Whatever you do to one side of an equation, do the same to the opposite side of the equation. In simple words, to solve an equation is to isolate by making its coefficient equal to 1. The variable is left on one side, and everything else is on the other side of the equation. Solving an algebraic equation is generally the procedure of manipulating an equation. Expressions in an equation can be related by equals to sign (=), less than (), or a combination of these signs. This article will learn how to solve an equation by performing the four basic mathematical operations: addition, subtraction, multiplication, and division.Īn equation is generally composed of two expressions separated by a sign that indicates their relationship. Therefore, students need to become more proficient in how to go about the operation. The solutions for most of the algebraic expressions are sought by applying this skill. Understanding how to solve equations is one of the most fundamental skills each student studying algebra can master. Solving Equations – Techniques & Examples
