Sauron [17]4 years ago

7 0

Answer:

Step-by-step explanation:

17)-8(5-n)=-96

-8*(5-n)-(-96)=0

(0 - 8 • (5 - n)) - -96 = 0

8n + 56 = 8 • (n + 7)

8 • (n + 7) = 0

Solve : 8 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solve : n+7 = 0

Subtract 7 from both sides of the equation :

n = -7

n = -7 is your answer
