Question

There is a fixed value of x, and a value of y to go with it, which make all five expressions equal in value.

Can you find the x, y pair?

2x + 3y - 20
5x - 2y + 38
4x + 5y - 72
x - 4y + 108
3x - y + 39

Every time I try I can't figure out what the value of X. Could someone see if they could find out what X is?
