Question

How do you simplify `(16 - 13x) + (10x - 11)`?

Answer 1

`5-3x`

Explanation:

The first parenthesis does not really do anything, it is as if we are multiplying that expression by "`1`." And because there is a `+` sign on the outside of the second parenthesis, we may also "remove" the parenthesis without affecting our final result.

`(16-13x)+(10x-11)=16-13x+10x-11`

Putting the like terms together,
`=16-11-13x+10x=5-3x`.
