Let's replace the ? with an 'x'


1%2F3%2Bx=4%2F9 Start with the given equation.


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


3%2B9x=4 Distribute and multiply.


9x=4-3 Subtract 3 from both sides.


9x=1 Combine like terms on the right side.


x=%281%29%2F%289%29 Divide both sides by 9 to isolate x.
