Question 601880
Hello, 
Let's do substitution with these. 
6x+8y=14
xy=-12
Rewrite the second equation as:
x=-12/y
Plug this into the first:
6(-12/y)+8y=14
Multiply by y:
-72+8y^2=14y
Rearrange:
8y^2-14y-72=0
Factor this as:
2(4y+9)(y-4)=0
Solve for y:
y=4
y=-9/4
Plug 4 into the original equation:
x=-3
The other is:
x=16/3
Make sense?
