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
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

2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
s = 7, t = -3
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 only because we count in tens - and 5 10 and 2 are factors.
The difference between the number of 2s and the number of 4s in a sum.
16s + 4s = 20s
