Andre is trying to solve the equation 2x plus 6 equals 3x minus 8. The result of Andre’s first step was -x + 6 = -8. What was Andre’s first step?

Answer:
C. Subtracted 3x from each side.
Step-by-step explanation:
I'm not 100% sure that this is correct but it's the only one that makes sense in my brain. But I'm going to explain anyways.
2x + 6 = 3x - 8 (initial equation)
It could also be D. Subtract 6 from each side, which is why I'm confused. Hopefully this helps, sorry if it doesn't. But happy holidays! :))
