Let's simplify step-by-step.7(9x−3)−4(2x−1)

Distribute:=(7)(9x)+(7)(−3)+(−4)(2x)+(−4)(−1)=63x+−21+−8x+4

Combine Like Terms:=63x+−21+−8x+4=(63x+−8x)+(−21+4)=55x+−17

Answer:=55x−17

First we distribute
7(9x-3) - 4(2x-1)
63x - 21 - 8x + 4
then we combine like terms
55x - 17
The answer is the second one

Hope this helps :)
