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

A. (2,5)
B. (2,-5)
C. (-1,1)
D. (1,-1)


PLEASE EXPLAIN AND SHOW HOW YOU DID IT THANKS!

y = -2x - 1 and y = 3 - 4x

so -2x - 1 = 3 - 4x

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


y = -2x - 1 = -2*2 - 1 = -5

B is the answer

Rewrite both equations to y= form
The first equation you rewrite to read y=-2x-1
The second equation you rewrite to read y=-4x+3
Now just set them equal to each other.
Plug the x back into either equation and you get B
(2, -5)

B (2,-5) first you convert the equations to y=mx+b form.
y=-2x-1 and
y=-4x+3
then you graph them with either a graphing calculator or graphing paper and find the intersection
