B?

Which equation has solution x = -3?
A) 2x - 7 = -1
B) 3x + 8 = 1
C) 1/2x + 8 = 10
D) 1/2 (2x - 6) = -6

Not B: 3(-3)+8 = -9+8 = -1

Answer to this question is

1/2(2x-6)=-6

hope this helps

To find the equation that has a solution of x = -3, we need to substitute -3 into each equation and check which equation satisfies this value.

Let's test each equation:

A) 2x - 7 = -1
Substituting x = -3: 2(-3) - 7 = -6 - 7 = -13 (not equal to -3)

B) 3x + 8 = 1
Substituting x = -3: 3(-3) + 8 = -9 + 8 = -1 (not equal to -3)

C) 1/2x + 8 = 10
Substituting x = -3: 1/2(-3) + 8 = -3/2 + 8 = 13/2 (not equal to -3)

D) 1/2(2x - 6) = -6
Substituting x = -3: 1/2(2(-3) - 6) = 1/2(-12) = -6 (equal to -3)

Therefore, the equation that has a solution of x = -3 is D) 1/2(2x - 6) = -6.
