What do I do to solve this?

First let's write it down, 

 x + (2x - 3) + (3x - 5) 

Then remove the parentheses

 x + 2x - 3 + 3x - 5 

 first combine the x + 2x = 3x to obtain: 3x - 3 + 3x - 5 

 then combine the 3x + 3x = 6x to obtain: 

 6x - 3 - 5 

rewrite 6x - 3 - 5 as 6x + (-3) + (-5) 

And the answer would be 6x + (-8) = 

6x - 8

I hope my answer helped you
