Question

-3x - 5+1 and 8x - 2x -9

Answer 1

This is NOT a question.  If is two expressions, each of which could be simplified by COMBINING 'LIKE' TERMS.

When you do that (e.g -5 + 1 becomes merely -4), you will still have two different expressions, albeit simplified.

Answer 2

Combine like terms.

 

-3x - 5 + 1

-3x - 4

 

8x - 2x - 9

6x - 9
