Question

2. Solve the following equation for c. (5 points)
-8(1 + 4c) + 7c = -25 - 80
C=​

Answer 1

c=1

Explanation:

Simplify both sides of the equation first.

−8(1+4c)+7c=−25−8c

(−8)(1)+(−8)(4c)+7c=−25+−8c

−8+−32c+7c=−25+−8c

(−32c+7c)+(−8)=−8c−25

−25c+−8=−8c−25

−25c−8=−8c−25

Add 8 to both sides.

−17c−8+8=−25+8

−17c=−17

Divide both sides by -17.

-17c/-17 = -17/-17

c=1
