A + b = d+c
<span>a - b = e - c </span>
The b and c cancel out.
<span>2a = d+e </span>
<span>a = (d+e)/2 </span>
This is what I’m trying to figure out

The required division equation will be :
Sorry, I didn't fully understand your initial question. I'll answer it now.
A quick and easy equation you can always use is y = -x + 2
Put one point on (0, 2) and put another point on (2, 0) (since a slope of 2/2 would cancel out) Then connect the points, and you're done.
Answer:
Step-by-step explanation:
Option A is the correct answer
256 x 343 / 7 x 64
