Question

Find the solution of x – 13 = 25, and verify your solution using substitution.

options:

A)

x = 12, 12 + 13 = 25, 25 = 25

B)

x = 39, 39 – 13 = 25, 25 = 25

C)

x = 37, 37 – 13 = 25, 25 = 25

D)

x = 38, 38 – 13 = 25, 25 = 25

Answer 1

x = 38

Explanation:

x-13 = 25

Add 13 to each side

x-13+13 = 25+13

x = 38

Check

38-13 = 25

25=25
