The solutions are: s = -3/2 and s = -3/2 they have equal roots
The simplified expression is 40 - 12s
12 + 12 + 12 + 12 equals 48. This can be calculated by adding each pair of 12s together, which results in 24, and then adding the remaining 12s together to get the final answer of 48.
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)
