Answer:  Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.

Here's how:

Step-by-step explanation:

19−4c=17

19 - 19 - 4c = 17 - 19  Subtract 19 from both sides  19-19 =0 Cancels on the left

-4c = 17-19   subtract: 17-19 = -2

-4c = -2

-4c/4 = -2/-4    Divide both sides by -4  

Negatives divided by Negatives have a Positive quotient  -4/-4 =1, Cancels

c = 1/2
