Respuesta :
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
-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
