Help PLEASE?

What is the solution of the system?

1. 4x-y= -3
6x - y= -8
-(5,5.5)
-(-2.5,-7)
-(-2.5,2.2)
-(2.5,-7)

2. 5x + 7y= 32
8x + 6y= 46

Answer 1

what class is this?

Answer 2

Algebra 1

Answer 3

ok im in algebra 2 gimme a sec

Answer 4

Alright

Answer 5

now are your answers being multiplied my (-) or is that just hashmarks showing each individual answer?

Answer 6

Just showing the answers

Answer 7

Oh ok i was gonna say, this is complicated algebra 1 stuff. ok im gonna show you how to do the first then let you try the second. does that sound good?

Answer 8

Yes

Answer 9

so here is what you do to find your answer. first take your first equation: 4x-y= -3
then pick any of the answers, so lets go with A: (5,5.5)
plug-in your co-ordinates. 4(5)-(5.5)=-3
multiply: 20-5.5=-3
since 14.5 does not equal -3, you go with the next one. think you got it?

Answer 10

Then if a answer works, make sure to test it on both equations before choosing it

Answer 11

so for the first one your answer would be B
