= 2a - 1
2(
) = 2(2a - 1) <em>multiplied both sides by 2 </em>
ab = 4a - 2 <em>distributed the 2 on the right side</em>
ab - 4a = -2 <em>subtracted 4a from both sides</em>
a(b - 4) = -2 factored out "a" from the left side
a =
<em>divided (b - 4) on both sides</em>
Answer: a =
3c + b.....when c = -7 and b = 4
3(-7) + 4 =
-21 + 4 =
- 17 <===
It’s B because they both equal each other I would explain more but I’m in class but the answer is definitely B
