Question

Maria solved the equation below and got x = –4. Which of the following choices verifies that her solution is correct?



5x + 22 = x + 6




A.

5(–4) + 22 = (–4) + 6

–20 + 22 = –2


–2 = –2



B.


5(–31) + 22 = (–10) + 6

–26 + 22 = –4

–4 = –4




C.


5(–4) + 22 = (–4) + 6

5(18) = (–4) +6

24 = 24




D.

5(–4) + 22 = (–4) + 6

–20 + 22 = 2

2 = 2
