Answer:

C

Step-by-step explanation:

So if x is the number, then 4 times the number would be 4x and adding that to -8 would be 4x + (-8) and then 12 times the number would be 12x, so you have 4x + (-8) = 12.

Then, solve:

[tex]4x - 8 = 12x\\[/tex]

subtract 4x from both sides

[tex]-8 = 8x[/tex]

divide both sides by 8

[tex]-1 = x \\x = -1[/tex]
