Now looking at the equation we need to substitute in for, it would be easier for us to plug something in with a denominator of 5 so they would cancel out and we can do a little less math. So we shall solve for y in this equation.

Now we plug this y into the other equation.

Now we plug this into the other equation.

My calculator isn't working right now so I can't quite give you decimal values but those fractions should be correct.
