Exercise 20 Page 46

Start by subtracting 5 from both sides.

y=2x-2

Practice makes perfect

To solve the given literal equation for y, we will use the Properties of Equality to apply inverse operations on the equation.

8x-3=5+4y

LHS-5=RHS-5

8x-3-5=5+4y-5

Subtract terms

8x-8=4y

.LHS /4.=.RHS /4.

8x-8/4=4y/4

Write as a difference of fractions

8x/4-8/4=4y/4

Calculate quotient

2x-2=y

Rearrange equation

y=2x-2
