1/3h - 4(2/3h-3) = 2/3h -6
first distribute to take away the parenthesis
1/3h - 8/3h + 12 = 2/3h -6
there are different ways to go about this but i would multiply everything by 3h to just take away all those denominators, making it simpler to solve
1 - 8 +12(3h) = 2 - 6(3h)
simplify
-7 + 36h = 2- 18h
simplify
+7 +18h +7 +18h
54h = 9
/54 /54
h = 9/54
h = 1/6
