-12-4c=6\left(3-c\right)
Use the distributive property to multiply -4 by 3+c.
-12-4c=18-6c
Use the distributive property to multiply 6 by 3-c.
-12-4c+6c=18
Add 6c to both sides.
-12+2c=18
Combine -4c and 6c to get 2c.
2c=18+12
Add 12 to both sides.
2c=30
Add 18 and 12 to get 30.
c=\frac{30}{2}
Divide both sides by 2.
c=15
Divide 30 by 2 to get 15.
