Exercise 55 Page 638

Apply inverse operations to isolate y.

B

Practice makes perfect

Rewriting any linear equation in the slope-intercept form requires us to isolate the y-variable. To do this, we will use the Properties of Equality to apply inverse operations on the equation.

2x+5y=40

SubEqn

LHS-2x=RHS-2x

5y=40-2x

DivEqn

.LHS /5.=.RHS /5.

y=40-2x/5
