2x%2F3-5=7 Start with the given equation.


3%282x%2Fcross%283%29%29-3%285%29=3%287%29 Multiply EVERY term by the LCD 3 to clear the fraction.


2x-15=21 Multiply and simplify.


2x=21%2B15 Add 15 to both sides.


2x=36 Combine like terms on the right side.


x=%2836%29%2F%282%29 Divide both sides by 2 to isolate x.


x=18 Reduce.
