Answer 1

\(2x+y=-11\\
3x-4y=11\)

If we solve the top equation for \(y\) we have,
\(y=-2x-11\)

You then plug that into the sectiond equation where \(y\) is.
\(3x-4(-2x-11)=11\)

Distribute.
\(3x+8x+44=11\rightarrow 11x=-33\)
\(x=-3\)

Then you plug that back into either of the original equations and solve for \(y\) ! :)

Answer 2

Yes, but you need to know how to get the whole answer, not just extrapolate from part of the answer.

Answer 3

2x + y = -11---(1)
3x - 4y = 11---(2)

in equation (1)

2x+y=-11
2x=-11-y
x=-11-y/2

put in equation (2)

3(-11-y/2)-4y=11
-33-3y/2-4y=11
-33-3y-8y=22
-33-11y=22
-11y=22+33
-11y=55
y=-55/11
y=-5

put in equation (1)

2x + y = -11
2x-5=-11
2x=-11+5
2x=-6
x=-3

Answer 4

Yeah I plugged it in and got y = -5 and x = -3 thank you both <3 I don't know who to give the medal to but I'll fan you both

Answer 5

My Pleasure.

Answer 6

No problemo!

Answer 7

I have two more like these that I need some help on, i believe i have the answers to them but i'm not sure i'll put them up if you'd take a look at them

Answer 8

Sure.
