Question

Please help.
I can't figure this out.

Answer 1

that's not a system right?
maybe it means solve the first equation for x and the 2nd for y O.o

Answer 2

That what it means but I can't figure out how to write the answer.

Answer 3

Sorry..I don't think I understand that :/

Answer 4

MMMK

Answer 5

The only thing I can think of is to solve x and y in terms of A and B.

I got

y = (5B+A)/7
x = (-2B+A)/7

Answer 6

I'll try it.

Answer 7

Nope

Answer 8

Try could try this

x = (A+B)/-7
y = (-5A +2B)/7

I don't know. This is a weird question.

Answer 9

Ya, I have two like this.

Answer 10

your answer has to have an A and a B in it

Answer 11

They do

Answer 12

If you want I can walk you through my thinking process

3x + 2y = A
5x +y = B

subtract 5x from both sides of the second equation

y = B-5x

plug it into the first

3x +2(B-5x) = A

3x + 2B - 10x = A

-7x = A - 2B

x = (A-2B)/-7

plug that into the second equation

5((A-2B)/7) + y = B

(5A-10B)/7 + y = B

subtract (5A-10B)/7 from both sides

y = -5A/7 + 17B/7

y = (-5A + 17B)/7

so

x = (A-2B)/7

y = (-5A+17B)/7

Thanks for trying to help.
