To simplify this expression, we are going to combine like terms.
First, we can see that we have two terms with the variables [tex]xy[/tex] being multiplied together, [tex]2xy[/tex] and [tex]-xy[/tex]. Together, these add to [tex]xy[/tex], so our expression is now:
[tex]xy - 3yz + 5 + 2yz[/tex]
We also have two terms with [tex]yz[/tex], [tex]-3yz[/tex] and [tex]2yz[/tex]. Together, these add to [tex]-yz[/tex], so our expression is now:
[tex]xy - yz + 5[/tex]
Our final expression is xy - yz + 5.
