1/4 h + 9 = 3/4 h - 7

1/4 h - 3/4h = - 7 - 9

-1/2 h = - 16

h = 32

Remember you can do anything to an equation as long as you do it to both sides

try to get the unknown by itself

we hates fractions

times everybody by 4

h+36=3h-28

minus h both sides

36=2h-28

add 28 both sides

64=2h

divide both sides by 2

32=h
