Exercise 56 Page 369

Apply inverse operations to isolate y.

y=8/15x

Practice makes perfect

To solve the given equation for y, we will use the Properties of Equality to apply inverse operations on the equation. Remember, only like terms can be combined.

3/2y=4/5x

MultEqn

LHS * 2=RHS* 2

3y=(2)4/5x

Rewrite

Rewrite 2 as 2/1

3y=(2/1)4/5x

MultFrac
