add 14c to both sides
add 5 to both sides
Well first you have to combine the variables,
So lets start with the variable (the c),
Take the -14c and put it with the 4c on the left side,to do this, you will have to +14 onto the 4c, so the answer is 18c.
Next you have to get the numbers without variables on the right side,
To do this you have to take the -5 and put it with the +67, so you would change the -5 to +5 and add it to 67, the answer is 72.
So now you have-
18c=72
So finally you have to divide 18c by 18 and then 72 by 18.
The answer is c=4
