Will try elimination here.
2X - 7Y = 0
- 2(X - 6Y = - 5)
2X - 7Y = 0
- 2X + 12Y = 10
------------------------------add
5Y = 10
Y = 2
---------- find X ( second equation will do )
X - 6(2) = - 5
X - 12 = - 5
X = 7
-------------check both equations for consistancy
2(7) - 7(2) = 0
14 - 14 = 0
0 = 0
----------------first equation checks
7 - 6(2) = - 5
7 - 12 = - 5
- 5 = - 5
---------------------------both check and are consistent
(7, 2)
------------------ordered pair
