Opps I meant s= 4
The answer that you think you know is wrong. It will make no difference how you enter it; it will still be wrong.

4r -10s = -28
25r +10s = 115
29r = 87
r = 3
6 - 5s = -14
5s = 20
s = 4

You need a tutorial on how to solve simultaneous equations. Concentrate on learning the method.
I missed your correction and apologize for my remark. You obviously do know how to do this type of problem. I would just report the result as r=3 and s=4
