5x - 2y = 4 .......................... (1)
6x + 2y = 18 ....................... (2)

(2) + (1):
5x - 2y = 4 .................... (1)
+) 6x + 2y = 18 .................. (2)
———————————————
11x + 0y = 22

11x = 22

x = 22/11

x = 2


Sub x = 2 into (1):
5(2) - 2y = 4

10 - 2y = 4

-2y = 4 - 10

-2y = -6

y = -6/-2

y = 3
