Question

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

Answer 1

`u=15/2 or 7.5`

Explanation:

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`
