Answer:

Let me finish it :

7h - 15h + 40 = -72

(7h - 15h) + 40 = -72

-8h + 40 = -72

-8h = -72 - 40

-8h = -112

h = 8

So the value of h is 8

Hey there!

7h - 15h + 40 = -72

COMBINE the LIKE TERMS

-8h + 40 = -72

SUBTRACT 40 to BOTH SIDES

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

CANCEL out: 40 - 40 because it gives you 0

KEEP: -72 - 40 because it helps solve for the h-value

NEW EQUATION: -8h = -72 - 40

SIMPLIFY IT!

-8h = -112

DIVIDE -8 to BOTH SIDES

-8h/-8 = -112/-8

CANCEL out: -8/-8 because it gives you 1

KEEP: -112/-8 because it helps solve for the h-value (it gives you the result of it!)

NEW EQUATION: h = -112/-8

SIMPLIFY IT!

h = 14

Therefore, your answer is: h = 14

Good luck on your assignment and enjoy your day!
