Solving Equations with a Variable on Both Sides

Solve for X:

4x + 5 = 2x + 7

• 1/3

• 2/3

• 3

• 2

10x + 9 = 4x - 9

• x = 0

• x = 3

• x = -3

• x = -18

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable

• Be confused
