Question

What value of h makes the equation true? −18(2h+4)+12=−74

Answer 1

First of all solve the -18(2h+4)...
-36h-72+12 = -74

Then you can move values over from the left-hand side to the right-hand side.
-36h = -14

Then you divide both sides by 36 and change the signs around...

h = 14/36 = 7/18

Answer 2

You're answer is going to be h=7/18 (fraction)
