Use the method of elimination to solve
(x − 4)/3 + y = −2
(2y − 1)/7 + x = 6
-----
Simplify::
x-4 + 3y = -6
2y-1 + 7x = 42
----
Rearrange::
x + 3y = -2
7x + 2y = 43
-----------------
Modify for elimination:
7x + 21y = -14
7x + 2y = 43
----
19y = -57
y = -3
----
Solve for "x":
x +3y = -2
x -9 = -2
x = 7
