2s + 16 = 4s - 6
Subtract 2s from both sides: 16 = 2s - 6
Add 6 to both sides: 22 = 2s
divide both sides by 2: s = 11
It is a simple linear equation in 's'. Its solution is the number that 's' must bein order to make it a true statement. The solution may be found like this:4s + 10 = 2s + 2Subtract 10 from each side of the equation:4s = 2s - 8Subtract 2s from each side:2s = -8Divide each side by 2 :s = -4
Cant do much with this one.9r-4s / 9r+6s9r-4s / 3(3r+2s)
If that is l and not 1 then it is 3.5l+2s when simplified
how many 4s go in 16
2t-4s
2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
s = 7, t = -3

14s 2d 7 - 6s 4d 5 + 8s 2d 3/2s 2d = 14s 7 - 3s 2s 5 + 4s 3
The simplified expression is 40 - 12s
The difference between the number of 2s and the number of 4s in a sum.
