Question

6c + 14 = -5c + 4 + 9c c=

Answer 1

First gather c's to one side and the numerical value to the other side. When doing this the sign will be opposite when moving to the other side of the equation.

6c+5c-9c=4-14
2c=-10
c=-5

Answer 2

First combine like terms
6c + 14 = 4c + 4, then subtract 4c from both sides
2c + 14 = 4, then subtract 14 from both sides
2c = -10, then divide both sides by 2

C = -5
