Solve:<br> 3c - 15 = 17 - c<br> plsss helpp !! i put 20 pts on this !!
azamat

Answer:

c=8

Step-by-step explanation:

Simplifying

3c + -15 = 17 + -1c

Reorder the terms:

-15 + 3c = 17 + -1c

Solving

-15 + 3c = 17 + -1c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add 'c' to each side of the equation.

-15 + 3c + c = 17 + -1c + c

Combine like terms: 3c + c = 4c

-15 + 4c = 17 + -1c + c

Combine like terms: -1c + c = 0

-15 + 4c = 17 + 0

-15 + 4c = 17

Add '15' to each side of the equation.

-15 + 15 + 4c = 17 + 15

Combine like terms: -15 + 15 = 0

0 + 4c = 17 + 15

4c = 17 + 15

Combine like terms: 17 + 15 = 32

4c = 32

Divide each side by '4'.

c = 8

Simplifying

c = 8
