Hi Jennifer.
When you are given a "solution" as a paired value, it means you can substitute these values in for your x and y variables and the equation will work. I'll show you how to do this with a slightly different set of numbers and you can try it on your own numbers.
If a solution of the equation 3x = 26  cy is (6,4) then what is the value of c?
Solution: First substitute the value 6 for every x you see and substitute 4 for each y:
3x = 26  cy
3(6) = 26  c(4)
18 = 26  4c
Now solve for c by rearranging the equation:
4c = 26  18
4c = 8
c = 2
Hope this example helps you!
