To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.
Then, divide by 3 on each side.
So, c = 7.
The answer would be 3mph because 3/4 / 1/4 = 3. So the answer would be 3mph.

Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
