x%2F2%2Bx%2F5=7%2F10 Start with the given equation.


10%28x%2Fcross%282%29%2Bx%2Fcross%285%29%29=10%287%2Fcross%2810%29%29 Multiply both sides by the LCD 10 to clear any fractions.


5x%2B2x=7 Distribute and multiply.


7x=7 Combine like terms on the left side.


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


x=1 Reduce.
