<PRE><B>Question 601240</B>
{{{(2/3)a-1/2=3/5}}} Start with the given equation.



{{{30((2/cross(3))a-1/cross(2))=30(3/cross(5))}}} Multiply both sides by the LCD {{{30}}} to clear any fractions.



{{{20a-15=18}}} Distribute and multiply.



{{{20a=18+15}}} Add {{{15}}} to both sides.



{{{20a=33}}} Combine like terms on the right side.



{{{a=(33)/(20)}}} Divide both sides by {{{20}}} to isolate {{{a}}}.

Answer:


So the solution is {{{a=33/20}}} </PRE>
