Question 711679
-x+2y=-6 
8x+ y=31
-------------
You have a choice: solve the 1st equation for "x"
or solve the 2nd equation for "y":
-----
Solving for x you get:
x = 2y+6
----
Substitute for "x" in the 2nd equation and solve for "y":
8(2y+6)+y = 31
16y + 48 + y = 31
17y = -17
y = -1
-----------
Solve for "x" using x = 2y+6
x = 2*-1+6
x = 4
