Exercise 14 Page 193

Use the Subtraction Property of Equality to isolate y on the right-hand side of the equation.

y=8

Practice makes perfect

To solve the equation, we have to isolate y on one side. Here, we can use the Subtraction Property of Equality and subtract 12 from both sides of the equation. Let's do it!

20=y+12

LHS- 12=RHS- 12

20- 12=y+12- 12

Subtract terms

8=y

Rearrange equation

y=8
