Question

Simplify: 40-8(2x-1)

I know it's very simple, but I'm not sure of my first step.

Answer 1

Rewrite the 40.
Then distribute the -8 by what is inside the parentheses.
Then combine like terms.

Answer 2

I'm not sure if I did it correctly, but my answer was 64x-32.

Answer 3

Ok, here we go. One step at a time.

40 - 8(2x - 1)
= 40 - 8 * 2x - 8(-1)
= 40 - 16x + 8
= 48 - 16x
