Question
1/3s + 7/9 = 4/3s

Answer
The equation must be s/3 + 7/9 = 4s/3, right?

Multiply each term in the equation by 9.
This gives 3s + 7 = 12s.

To solve, subtract 3s from both sides.
This gives 7 = Cs, for some constant C.

Divide both sides by C and get s = 7/C.

Get what C is, and then you've got the answer.
