%281%2F3%29s%2B7%2F9=%284%2F3%29s Start with the given equation.


9%28%281%2Fcross%283%29%29s%2B7%2Fcross%289%29%29=9%28%284%2Fcross%283%29%29s%29 Multiply both sides by the LCD 9 to clear any fractions.


3s%2B7=12s Distribute and multiply.


3s=12s-7 Subtract 7 from both sides.


3s-12s=-7 Subtract 12s from both sides.


-9s=-7 Combine like terms on the left side.


s=%28-7%29%2F%28-9%29 Divide both sides by -9 to isolate s.


s=7%2F9 Reduce.


----------------------------------------------------------------------

Answer:

So the answer is s=7%2F9 which approximates to s=0.778.

solve this equation (1/3)s+(7/9)=(4/3)s
----------
lcm = 9
===============
Multiply thru by the lcm to get:
3s + 7 = 12s
9s = 7
s = 7/9
============
