Answer 2

PreeteBad... Do you have pencil and paper?

Answer 3

yes

Answer 4

multiply 1st equation by 3 and 2nd equation by 2

Answer 5

the solution is r=2 and s=9

Answer 6

I have a snap shot coming your way! lol

Answer 7

s = s

(12+3r)/2 = (31-2r)/3

3(12+3r) = 2(31-2s)
36+9r = 62 - 4r
13r = 26
r = 2

Answer 8

s = 9

Answer 9

so the solution is 9?

Answer 10

That's the same thing I got. I eliminated the s variable at the very beginning

Answer 11

The solution is (2,9)
