Question #00ec0

Answer 1

`4+14y`

Explanation:

`11+15y-7-y`
`11-7+15y-y`
`4+14y`

First, I re-arranged the order (make sure that you keep the correct signs in front of the constant or variable e.g. -y, +15y, -7 and +11).

Then, I simplified:

`11-7=4`
`15y-y=14y`

This is how you get the `4` and the `14y`.
