well; they tell you what y is "equal" to so use that value in the other equation and solve for x
So if y=5x+60, then you can plug that in for y in the other equation. So you get 4x - 6(5x + 60) = -22 Then solve for x. Then plug your answer in and solve for y in either equation.
the thing about a system of equations is that no matter where x and y are, their values never change
