2y - x = 3
y = -5x + 7
Rewrite the second
y + 5x = 7
Mutiply it by 2
2y + 10x = 14
Now subtract the first equation from this:
2y + 10x = 14
2y - x = 3
11x = 11
Divide both sides by 11: x = 1
Substitute for x in the first equation:
2y - 1 = 3
Add 1 to both sides: 2y = 4
Divide both sides by 2: y = 2
Answer: (x, y) = (1, 2)
