Question

Solve the equation.
7h-5(3h-8)=-72

Answer 1

4 hours

Explanation:

7h - 5(3h - 8) = -72 Distribute the -5

7h - 5(3h )(-5)(-8) = -72 A negative times a negative is a positive

7h - 15h + 40 = -72 Combine like terms

-8h + 40 = -72 Subtract 40 from both sides

-8h +40 - 40 = -72 - 40

-8h = -32 Divide both sides by -8

`(-8h)/(-8)` =
`(-32)/(-8)`

h = 4
