Answers
Answer:
Simplifying
6c + -22 = 3c + -7
Reorder the terms:
-22 + 6c = 3c + -7
Reorder the terms:
-22 + 6c = -7 + 3c
Solving
-22 + 6c = -7 + 3c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3c' to each side of the equation.
-22 + 6c + -3c = -7 + 3c + -3c
Combine like terms: 6c + -3c = 3c
-22 + 3c = -7 + 3c + -3c
Combine like terms: 3c + -3c = 0
-22 + 3c = -7 + 0
-22 + 3c = -7
Add '22' to each side of the equation.
-22 + 22 + 3c = -7 + 22
Combine like terms: -22 + 22 = 0
0 + 3c = -7 + 22
3c = -7 + 22
Combine like terms: -7 + 22 = 15
3c = 15
Divide each side by '3'.
c = 5
Simplifying
c = 5
