Question

y= -6x + 16

Answer 1

What is the question?

Answer 2

what is Y= -6x + 16
Y=4x -4

Answer 3

Are you wanting to find what x and y are?

Answer 4

yes

Answer 5

\[y=-6x+16\]\[y=4x-4\]\[-6x+16=4x-4\]\[-6x+6x+16+4=4x+6x-4+4\]\[20=10x\]\[x=\frac{ 20 }{ 10 }=2\]

Answer 6

Then you can take that value of x and plug it into either of your two original equations. The answer will give you y.

Answer 7

OMG! thank you!!

Answer 8

You're welcome. :)

Answer 9

Y= 8x - 11
Y= 3x - 1
what is y and x?

Answer 10

Ok, I'll walk you through this one.

You have y=8x-11 and y=3x-1. So you can say 8x-11=3x-1.

Now solve for x. :)

Answer 11

k thanks!

Answer 12

You're welcome. I'll hang around if you need any help. :)

Answer 13

ok. i know how to do the x part. but im confused on how to get the y. can u give me an example

Answer 14

No problem.

Let's say that 1y+2x=5 and 1y+3x=7

So then we can say that y=5-2x and y=7-3x

So then we have 5-2x=7-3x

So then we have\[5-5-2x+3x=7-5-3x+3x\]\[x=2\]Then we can take x=2 and put it back into either of the two original equations.
First:\[y+2(2)=5\]\[y=5-4=1\]Second:\[y+3(2)=7\]\[y=7-6=1\]But you only need to use one of the equations. Does that make sense?

Answer 15

yes. thanks
