what you would do in this situation is first, add like terms. but remember that we are trying to get the c's on one side, and the regular numbers on the other. so, 6c+5c-9c. i got this because i am moving all of the c's to the left side of the equal sign, but to be able to do this we have to change the signs in front of the ones we are moving, the same rule applies to when we move the regular numbers, too. so, 6c+5c-9c= 2c. so now, we have what goes on the left side of the equal sign (2c) now, we have to figure out what goes on the right side of the equal sign. 4-14= -10. so now, we have 2c=-10 we now have to divide -10 by 2 to get rid of the 2 with the c. we get c=-5 as our final answer.
