Question 93319
Solve for x. 
1st: x+2y= -1
2nd: 3x-4y= 27
------------
Solve 1st for x:
x = -2y-1
--------------
Substitute that into 2nd and solve for y:
3(-2y-1) - 4y = 27
-6y-3 -4y = 27
-10y = 30
y = -3
--------------
Substitute that into x = -2y-1 and solve for x:
x = -2*-3-1
x = 5
--------------
System solution:
x=5; y=-3
