Answer:

r = 3 2/3

s = -0.444333

Explanation:

Multiply the top equation by 2

14r - 6s = 52

2r - 6s = 8 Subtract the two equations

12r = 44 Divide by 12

r = 44/12

r = 3 8/12

r = 3 2/3

2r - 6s = 8

2*(2 2/3) - 6s = 8

2*2.6667 - 6s = 8

5.3334 - 6s = 8 Subtract 5.3334 from both sides.

- 6s = 2 2/3 Divide by - 6

s = - 0.4443333
