Hello there!

a(b - c) = d
ab - ac = d
We need to add -ab to both sides
ab - ac - ab = d - ab
-ac = d - ab
To get c, we must divide both sides by -a
-ac/-a = (d - ab)/-a
c = (ab - d)/a

The correct answer is the first option.

Good luck!

a(b - c) = d
ab - ac = d
-ac = -ab + d
ac = ab - d
ac/a = (ab - d)/a
c = (ab - d)/a

Your answer will be A. c = (ab - d)/a. Hope this helps!
