The solutions are: s = -3/2 and s = -3/2 they have equal roots
The simplified expression is 40 - 12s
9s+6s-12s=24... Ignore the 's' for a moment giving the sum 9+6-12=24 - This results in the answer 3 x 'something' = 24. Therefore s=8 !
It is 4r + 12s
three 12s is 36
5/6s + 3/4 = 11/12 10/12s + 9/12 = 11/12 10/12s = (11 - 9)/12 10/s = 2 s = 5
26 divided by 12 equals 2 with a remainder of 2.
12r - 15s - r + 3s = 11r -12s
That's 60rs + 24s, which factors to 12s(5r + 2)

you - 54 in 12s
