Exercise 85 Page 213

To solve the equation, isolate w on one side of the equation.

w=5

Practice makes perfect

To solve the equation we have to isolate w on one side. We will begin by moving all variable terms to the right-hand side and all constants to the left-hand side.

3w+2=4w-3

SubEqn

LHS-3w=RHS-3w

3w+2-3w=4w-3-3w

SubTerm

Subtract term

2=w-3

AddEqn

LHS+3=RHS+3

2+3=w-3+3
