Solve the equation: 2/3x - 1/4 = 1/2x + 3

• x = 24

• x = 19.5

• x = 12

• x = 30

Solve the equation: 1/2x + 3 = 2/3x - 4

• x = 30

• x = 20

• x = 25

• x = 42

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
