Distribute
-12 -6a = -48
Add 12 to isolate -6a
-6a = -36
Divide by -6 on both sides to isolate a
a = 6
In the problems A-F, You multiply each of the numbers by itself. Like 9²=9×9=81
3³=3×3×3=27 6³=6×6×6=216 and so on for the other problems
G-I is 36=6² 100=10² and so on the cube is the same except you multiply the number three times by itself. I hope this helped a bit. Just ask if you still don't understand.
