x%2F7-x%2F9=4 Start with the given equation.


63%28x%2Fcross%287%29-x%2Fcross%289%29%29=63%284%29 Multiply both sides by the LCD 63 to clear any fractions.


9x-7x=252 Distribute and multiply.


2x=252 Combine like terms on the left side.


x=%28252%29%2F%282%29 Divide both sides by 2 to isolate x.


x=126 Reduce.
