Question 823982
{{{(5/4)u=1/12+(2/3)u}}} Start with the given equation.



{{{12((5/cross(4))u)=12(1/cross(12)+(2/cross(3))u)}}} Multiply both sides by the LCD {{{12}}} to clear any fractions.



{{{15u=1+8u}}} Distribute and multiply.



{{{15u-8u=1}}} Subtract {{{8u}}} from both sides.



{{{7u=1}}} Combine like terms on the left side.



{{{u=(1)/(7)}}} Divide both sides by {{{7}}} to isolate {{{u}}}.

Answer:


So the solution is {{{u=1/7}}}
