Answer 2

For this case, we have the following expression:

`-3x + x + 5`

We simplify the expression:

If we add similar terms, taking into account that different signs are subtracted and the sign of the greater one is placed, we have that
`-3x + x = -2x`

So, we have to:

`-3x + x + 5 = -2x + 5`

Answer:

-3x + x + 5 = -2x + 5
