Exercise 5 Page 192

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

m=25

Practice makes perfect

To solve the equation, we have to isolate m on one side. Here, we can use the Subtraction Property of Equality and subtract 24 from both sides of the equation. Let's do it!

24+m=49

LHS- 24=RHS- 24

24+m- 24=49- 24
