Question

@vocaloid is it A and C?

Answer 1

@Vocaloid

Answer 2

hold on a sec

8x - 12 - 4x = 4x - 12

Answer 3

now, in order to have one solution only, the two sides cannot be equal, so 4x-12 is not the answer

also, 4(x-5) is also out, because if we set 4x - 12 = 4(x-5) we get no solution

so the only possibilites are B and C

Answer 4

Ok. I see it now

Answer 5
