7/18

Explanation:

first, multply through by -18:

-36h-72 + 12 = -74

...add 72 to both sides

-36h + 12 = -2

...subtract 12 from both sids:

-36h = -14

...divide both sides by -36:

h = (-14)/-36 = 7/18 = 0.3888...

Always check your work.

-18(2 * (7/18) + 4) + 12 =

-18(14/18 + 72/18) + 12 =

-86 + 12 = -74
