Question 542123
{{{a/2-a/12=-5a/4}}} Start with the given equation.



{{{12(a/cross(2)-a/cross(12))=12(-5a/cross(4))}}} Multiply both sides by the LCD {{{12}}} to clear any fractions.



{{{6a-1a=-15a}}} Distribute and multiply.



{{{5a=-15a}}} Combine like terms on the left side.



{{{5a+15a=0}}} Add {{{15a}}} to both sides.



{{{20a=0}}} Combine like terms on the left side.



{{{a=(0)/(20)}}} Divide both sides by {{{20}}} to isolate {{{a}}}.



{{{a=0}}} Reduce.

Answer:


So the solution is {{{a=0}}}
