Exercise 13 Page 193

Use the Addition Property of Equality to isolate x on the left-hand side of the equation.

x=76

Practice makes perfect

To solve the equation, we have to isolate x on one side. Here, we can start by adding 16 to both sides of the equation using the Addition Property of Equality. This means that we can fill the first two boxes with 16. 60 &= x - 16 60 +16 &= x - 16 +16 x &=Now, let's perform the addition to find the value of x.

60+16=x-16+16

Add terms

76=x

Rearrange equation

x=76

The value of x is 76. We can write this value in the last box. 60 &= x - 16 60 +16 &= x - 16 +16 x &= 76
