Question 203457
{{{(3x+1)/x}}}
The short answer: "un-add" the fractions:
{{{(3x)/x+1/x}}}
Usually we add fractions like these which results is the original expression. But here, as we will see, reversing the process gets us to the desired answer quickly.
In the first fraction the x's cancel:
{{{3/1+1/x}}}
{{{3+1/x}}}
And we're done!
