Step-by-step explanation:
Simplifying
(3h + 18) = (15h)
Reorder the terms:
(18 + 3h) = (15h)
Remove parenthesis around (18 + 3h)
18 + 3h = (15h)
Solving
18 + 3h = (15h)
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Add '(-15h)' to each side of the equation.
18 + 3h + (-15h) = (15h) + (-15h)
Combine like terms: 3h + (-15h) = -12h
18 + -12h = (15h) + (-15h)
Combine like terms: (15h) + (-15h) = 0
18 + -12h = 0
Add '-18' to each side of the equation.
18 + -18 + -12h = 0 + -18
Combine like terms: 18 + -18 = 0
0 + -12h = 0 + -18
-12h = 0 + -18
Combine like terms: 0 + -18 = -18
-12h = -18
Divide each side by '-12'.
h = 1.5
Simplifying
h = 1.5
