Plug the first equation into the second equation.
4(1/4+2) - x = 60
Multiply everything in the parenthesis by 4.
1 + 8 - x = 60
Combine like terms.
9 - x = 60
Subtract 9 from both sides.
-x = 51
Divide -1 on both sides.
x = -51

Plug -51 into the second equation.

4y -(-51) = 60

4y + 51 = 60

Subtract 51 from both sides.

4y = 9

Divide 4 on both sides.

y = 2.25

The solution is (-51,2.25)
