%281%2F2%29x%2B9%2F14=3%2F7 Start with the given equation.


14%28%281%2Fcross%282%29%29x%2B9%2Fcross%2814%29%29=14%283%2Fcross%287%29%29 Multiply both sides by the LCD 14 to clear any fractions.


7x%2B9=6 Distribute and multiply.


7x=6-9 Subtract 9 from both sides.


7x=-3 Combine like terms on the right side.


x=%28-3%29%2F%287%29 Divide both sides by 7 to isolate x.

Answer:

So the solution is x=-3%2F7 which approximates to x=-0.429.
