<PRE><B>Question 784720</B>
{{{x/2-x/5=3}}} Start with the given equation.



{{{10(x/cross(2)-x/cross(5))=10(3)}}} Multiply both sides by the LCD {{{10}}} to clear any fractions.



{{{5x-2x=30}}} Distribute and multiply.



{{{3x=30}}} Combine like terms on the left side.



{{{x=(30)/(3)}}} Divide both sides by {{{3}}} to isolate {{{x}}}.



{{{x=10}}} Reduce.

Answer:


So the solution is {{{x=10}}}
