Can someone teach me how to do it plz.

You have the equation . To solve for the variable c, you need to get c on one side by itself to equal something. So the final answer should be
c = (some number).

The first step is to multiply both sides by 13. This will cancel the 13 in the denominator of the left side because 13/13 = 1.


Almost there... now we have to move the -2 to the other side. We can do this by adding 2 to both sides of the equation.

Im not that good with division but i think 5 is -6but dont quote me on thatim not the best in division but thats my answer
