Simplified its 12r+3s
-6r - s
No because 16s+20t when factored is 4(4s+5t)

2hno3+3h2s --> 3s+2no+4h2o
2h2s + so2 ----------> 3s + 2h2o
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
5 + 2s + s = 3s - s + 8 Combining like terms on the same side: 5 + 3s = 2s + 8 Subtracting 2s from both sides: 5 + s = 8 Subtracting 5 from both sides: s = 3
