Variables on Both Sides of the Equation
Solving Equations with variables on both sides of the Equals
3-5 Solving Equations with the variable on each side Objective: Students will solve equations with the variable on each side and equations with grouping.
Solve an equation with variables on both sides
Solve an absolute value equation EXAMPLE 2 SOLUTION Rewrite the absolute value equation as two equations. Then solve each equation separately. x – 3 =
Solve an equation using subtraction EXAMPLE 1 Solve x + 7 = 4. x + 7 = 4x + 7 = 4 Write original equation. x + 7 – 7 = 4 – 7 Use subtraction property of.
Standardized Test Practice
Solving Equations with variables on both sides of the Equals Chapter 3.5.
Lesson 2-4. Many equations contain variables on each side. To solve these equations, FIRST use addition and subtraction to write an equivalent equation.
Equations & Brackets.. You are now going to solve more complex equations by combining together two ideas that you have seen already. Try the following.

Objective The student will be able to: solve two-step inequalities.
Solving Equations Medina1 Variables on Both Sides.
Solving Multi- Step Equations. And we don’t know “Y” either!!
Solve an equation by combining like terms EXAMPLE 1 8x – 3x – 10 = 20 Write original equation. 5x – 10 = 20 Combine like terms. 5x – =
Solving Equations Medina1 Multi-Step Equations. Steps to solve Medina2 3. Use inverse of addition or subtraction You may not have to do all the steps.
Solve an equation using addition EXAMPLE 2 Solve x – 12 = 3. Horizontal format Vertical format x– 12 = 3 Write original equation. x – 12 = 3 Add 12 to.
Example 1 Solving Two-Step Equations SOLUTION a. 12x2x + 5 = Write original equation. 112x2x + – = 15 – Subtract 1 from each side. (Subtraction property.
