Answer:

A. Divide both sides of the equation by 3, and then subtract 6 from both sides of the equation. The solution is x = 1.

Step-by-step explanation:

3(x + 6) = 21

Divide both sides by 3

(x + 6) = 7

Subtract 6 from each side

x = 7-6

x=1

The first problem Levi solves is incorrect, because 5/4 is not equal to 20.

The second problem Levi solves is correct, because 1.5 x 10 is 15, which subtracting 8 is equal to 7.

The third problem Levi solves is correct, because 4 x 13 is 52 and plus 6 it is 58.

I hope this helps!
