Question 405203
solve using elimination method
3r-5s=-15
5r+3s=43
--------
Multiply 1st by 5 and 2nd by 3 to get:
15r - 25s = -75
15r +  9s = 129
---------
Subtract the top from the bottom and solve for "s":
34s = 204
s = 6
----
Solve for "r":
3r-5s = -15
3r - 5*6 = -15
3r = 15
r = 5
=======
Solution: r = 5; s=6
