x%2F9%2B3=7-x%2F3 Start with the given equation.


9%28x%2Fcross%289%29%2B3%29=9%287-x%2Fcross%283%29%29 Multiply both sides by the LCD 9 to clear any fractions.


x%2B27=63-3x Distribute and multiply.


x=63-3x-27 Subtract 27 from both sides.


x%2B3x=63-27 Add 3x to both sides.


4x=63-27 Combine like terms on the left side.


4x=36 Combine like terms on the right side.


x=%2836%29%2F%284%29 Divide both sides by 4 to isolate x.


x=9 Reduce.
