Question

How do you solve `1/5 + x=7/12`?

Answer 1

`x = 23/60`

Explanation:

The `(1/5)` is positive, so its passed to the other side as negative:
`x = 7/12 - 1/5`

Then, you should take the minimum between `5` and `12`:
`x = 5*7/60 - 12*1/60`
`x = (35 - 12)/60`
`x = 23/60`

Since 23 is a prime number, the fraction can't be more simplified than that.
