%282%2F3%29a-1%2F2=3%2F5 Start with the given equation.


30%28%282%2Fcross%283%29%29a-1%2Fcross%282%29%29=30%283%2Fcross%285%29%29 Multiply both sides by the LCD 30 to clear any fractions.


20a-15=18 Distribute and multiply.


20a=18%2B15 Add 15 to both sides.


20a=33 Combine like terms on the right side.


a=%2833%29%2F%2820%29 Divide both sides by 20 to isolate a.
