Question

at what point do the lines represented by the equations 2x+y+1=0 and 4x+y-3=0 intersect?

Answer 1

(2, -5)

Answer 2

Y=-2x-1
y=-4x+3
-2x-1=-4x+3
2x=4
x=2
y=-3

Answer 3

I agree with the work Radar shows, just when you substitute x back into your original equation, you should get y=-5 instead of -3.
