Question 401034
I need help with this question please. I have done the work but I get stuck when it comes to plugging it back into the equation.
2x+3y= -4
4x+y= -3
I have:
-4x+6y= -8  (I think you made an error here when you multiplied the first equation by -2. The result should have been -4x-6y=8
 
You should have had these two equations to work with,

-4x-6y=8
 4x+y=-3
add the equations
-5y=5
y=-1
substitute back into either equation, using the first,
2x+3y= -4
=2x+3*(-1)=-4
=2x-3=-4
=2x=-1
x=-1/2

ans: x=-1/2, y=-1 (This is where the two straight-line equation intersect.
see the graph below:
