x%2F2%2B3%2F4=7 Start with the given equation.


4%28x%2Fcross%282%29%2B3%2Fcross%284%29%29=4%287%29 Multiply both sides by the LCD 4 to clear any fractions.


2x%2B3=28 Distribute and multiply.


2x=28-3 Subtract 3 from both sides.


2x=25 Combine like terms on the right side.


x=%2825%29%2F%282%29 Divide both sides by 2 to isolate x.
