Question

10(c–1)=80 i need help

Answer 1

C =9

Explanation:

10(c−1)=80

Step 1: Simplify both sides of the equation.

10(c−1)=80

(10)(c)+(10)(−1)=80(Distribute)

10c+−10=80

10c−10=80

Step 2: Add 10 to both sides.

10c−10+10=80+10

10c=90

Step 3: Divide both sides by 10.

10c

10

=

90

10

c=9
