Answer:
Step-by-step explanation:
Isolate the term of h from one side of the equation.
Use the distributive property.
<u>Distributive property:</u>
→ A(B+C)=AB+AC
<h3>7h-5(3h-8)=-72</h3><u>First, multiply expand.</u>
⇒ -5(3h-8)
⇒ -5*3h=-15h
⇒ -5*8=40
<u>Rewrite the problem.</u>
→ -15h+40
⇒ 7h-15h+40=-72
⇒ 7h-15h=-8h
→ -8h+40=-72
<u>Subtract by 40 from both sides.</u>
⇒ -8h+40-40=-72-40
<u>Solve.</u>
⇒ -72-40=-112
⇒ -8h=-112
<u>Then, you divide by -8 from both sides.</u>
⇒ -8h/-8=-112/-8
<u>Solve.</u>
<u>Divide the numbers from left to right.</u>
→ -112/-8=14
- <u>Therefore, the correct answer is h=14.</u>
