The answer is very simple. Let me rewrite these equations for you.
1y - 1x = 03 ------------- (1)
4x - 1y = 60 ------------- (2)
I can rewrite (1) as
-1x + 1y = 03
4x - 1y = 60
When I add, 1y - 1y get cancelled, and 4x - 1x gives me 3x. Therefore,
3x = 63.
On further solving, we get, x = 63/3 = 21 and y = 3+21 = 24.
Thus, you solve this equation in this manner.
1y - 1x = 03 ------------- (1)
4x - 1y = 60 ------------- (2)
