Question

Find the solution of 7x = 35, and verify your solution using substitution.

A. x = 245; 7(35) = 245, 245 = 245
B. x = 6; 7(6) = 35, 35 = 35
C. x = 5; 7(5) = 35, 35 = 35
D. x = –5; 7(–5) = 35, –35 = –35

Answer 1

Answer: x = 7

Explanation:

In order to solve 7x = 35 you need to divide both sides by 7.

7x/7 = 35/7

x = 5

To verify your solution you multiply 7 x 5 = 35.
