This is an expression, so we can only simplify it as much as possible!

 

Do we see like terms? Yes, we see the \(x\) three times and they are all to the same degree, \(x^1\).

 

Therefore, we can add the coefficients of them and get \(2x-5y+5x+3x=2x+5x+3x-5y=10x-5y\) .

The expression is \(10x-5y\).

 

To simplify even more, if you want, we can factor out a 5.

\(10x-5y=5(2x-y)\)

 

You are very welcome!

:P
