$u=15/2 or 7.5$

We can solve this by putting everything on the left side on a common denominator. If you need me to explain how to do this, feel free to say so

$u/5+u/10-u/6=1$
$(6u)/30+(3u)/30-(5u)/30=1$
$(4u)/30=1$

Now that we have this, its a matter of multiplying and dividing to get $u$ by itself on one side:

$4u=30$
$u=30/4$
$u=15/2 or 7.5$

How do you solve u/5 + u/10 - u/6 = 1u/5 + u/10 - u/6 = 1?
