No idea what your equations are with all those "bouncing" equal signs
Am I looking at 4 equations?
Are there 2 different problems here?
Are you repeating the same equation -7x+5y=14 twice ?
Not going to start guessing. Re-post in a proper form

−7x+5y=14
6x-7y=7
-49x + 35y = 98
30x - 35y = 35
-------------------------
-19x = 133
x = -7
now use that to find y
6x-7y=7
-49x + 35y = 98
