The answer is A.
Rae made the error when she added 7.
The equation should be: -14 - 7 = 7x + 7 - 7
I cant follow what you've written but here is the correct solution with steps:-
-5x - 14 = 2x + 7
-5x - 2x - 14 = 2x - 2x + 7
-7x - 14 = 7
-7x - 7 - 14 = 7 - 7
-7x - 21 = 0
-7x -21 + 21 = 21
-7x = 21
-7x/-7 = 21 /-7
x = -3 answer
