Answer 2

Answer 3

wait are you talking to me or @WonderlandKy

Answer 4

i have the correct answer @WonderlandKy but i'm not going to give it to you you have to try to solve it too

Answer 5

@shinebrightlikeadimon of course, the problem who need trying is the Asker, not you

Answer 6

*person, not problem

Answer 7

Yes, I'm trying to find x and y. I know that you plug numbers in but I've done big numbers and small and can't seem to find numbers that fit both.

Answer 8

so your plunging in numbers and guessing?

Answer 9

and yah i feel the same way like i want people to teach me how to do it rather then give me the answer @Loser66

Answer 10

13x-2y=70
2x-2y=4

1) 13x-2y=70 --> rearrange to get 2y = 13x-70
Substitute that value for 2y into the 2nd equation:
2x-2y=4
2x - (13x-70) = 4
2x - 13x + 70 = 4
-11x = -66
x = 6

2) Now substitute this value for x into EITHER of the two original equations to solve for y...
13x-2y = 70
13(6) - 2y = 70
78 - 2y = 70
-2y = -8
y = 4

Solution set: \[\left\{ 6,4 \right\}\]

Answer 11

i agree with your answer ^^ but you should have at least let the asker try

Answer 12

I appreciate the input @shinebrightlikeadimon. However, having seen an example worked out fully, he/she can now use what they've learned and apply this method to additional problems going forward. Good luck, @WonderlandKy!
