Exercise 9 Page 192

Use the Subtraction Property of Equality to isolate d on the left-hand side of the equation.

d=4

Practice makes perfect

To solve the equation, we have to isolate d on one side. Here, we can use the Subtraction Property of Equality and subtract 11 from both sides of the equation. Let's do it!

d+11=15

LHS- 11=RHS- 11

d+11- 11=15- 11

Subtract terms

d=4
