Question

Consider the system:
9x-6y=78
-4y-14x=-68

Find X



I have attempted to work through the problem three times, and am having difficulty knowing exactly what to do. Thank you for your help. c:

Answer 1

9 x - 6 y = 78
14x + 4 y = 68
===============

18x - 12y = 156
42x + 12y = 204
----------------
60 x = 360
x = 6
9*6 -6y = 78
54 -78 = 6y
-24 = 6 y
y = -4

Answer 2

Thank you. :D
