Answer 2

can

Answer 3

is there more to the question?

Answer 4

Did this question have a chart?

Answer 5

no thats it

Answer 6

Try google?

Answer 7

o wait yes there is 1 sec

Answer 8

2x-y=-5
x+3y=22

Answer 9

yea so try plugging in x and y from each and which ever fits the equations is the answer

Answer 10

What you're going to do for this problem is find the ordered pair that can solve both equations. All you need to do is substitute the x and y values in both equations.

Answer 11

If you want I can help you with one of them.

Answer 12

ya

Answer 13

I think its A

Answer 14

lol i still dont get it (@_o)

Answer 15

Okay. So, I'll just start with the first answer, A.
(1, 7) x = 1, y = 7

For the first equation:
2x - y = -5
2 * 1 - 7 = - 5
2 - 7 = - 5
-5 = -5

Since both sides (of the equal sign) are... the same, or equal this pair does solve the first equation.

For the second equation:
x + 3y = 22
1 + 3 * 7 = 22
1 + 21 = 22
22 = 22

Again, both sides are equal. This means this pair is the solution for this equation.

I didn't mean to, but I actually found your answer, lol. Its A because its the proper solution for both equations.

Answer 16

2x1-7=-5
3-7=-5
-5
1+3x7=22
1+21
22

Answer 17

just plug them in using PEMDAS

Answer 18

Do you understand it now?
Oh, and if you need more help in the future just let me know. I'm always glad to help if I can. :3

Answer 19

ok thanks you guys i got it :)

Answer 20
