Question

How do you solve `\frac { f } { 5} = - 4`?

Answer 1

`f=-20`

Explanation:

We multiply both sides by `5` to cancel out the denominator on the left:
`(f*5)/5=-4*5`

`(f*cancel5)/cancel5=-4*5`

`f=-20`

We can also plug `-20` into the original expression to verify that it is correct:
`-20/5≟-4`

`-4=-4`
