If x = -1, which equation is true?
docker41 [41]
A. -3(-1) + 7 = 4
3 + 7 = 4
11 = 4 (wrong)

B. 4x - 8 = 12
4(-1) - 8 = 12
-4 - 8 = 12
-12 = 12 (wrong)

C. -2x + 3 = 1
-2(-1) + 3 = 1
2 + 3 = 1
5 = 1 (wrong)

D. 8x + 5 = -3
8(-1) + 5 = -3
-8 + 5 = -3
-3 = -3 (correct!)

So, in conclusion, D is the correct answer.
