Question

Show your reasoning. 2y=x-4 4x + 3y = 5 PLS HELP

Answer 1

Answer:

(2,-1)

divide both sides of the first equation by 2 to get y by itself. this gets you y=x/2-2

then plug that into the other equation:

4x+3(x/2-2)=5

SImplify that to get:

4x+3x/2-6=5

Add 6 to both sides:

4x+3x/2=11

give 4x a denominator of 2 as well:

8x/2+3x/2=11

add them:

11x/2=11

multiply both sides by 2/11 to get:

x=22/11 which simplifies to x=2

plug x into first equation:

2y=(2)-4

simplify:

2y=-2

divide both sides by 2 to get:

y=-2/2 which is the same as -1

x=2

y=-1

answer: (2,-1)

I hope this helps
