-6x-4+x=-26 --> -5x = -22 --> x = 22/5 *******************
x+y+6z=13
2x+4y+6z=30
================
x+y+6z=13
2x+4y+6z=30 divide by 2 --> x + 2y + 3z = 15
----
y + 6z = 13 - 22/5 = 43/5 Eqn A
2y + 3z = 15 - 22/5 = 53/5
----------------
2y + 12z = 86/5 Eqn A times 2
2y + 3z = 53/5
------------------- Subtract
9z = 33/5
z = 11/15 *********************
==================
2y + 3z = 53/5
2y + 11/5 = 53/5
y = 21/5 ********************
