Hello!
Let's simplify the expression
6-2x+5+4x
Combine like terms:
6+5-2x+4x
11+2x
And that's the final answer, because 11 and 2x are not like terms (and that's Tyler's error. He shouldn't have combined 11 and 2x.
This is the correct way to simplify:
6+5-2x+4x
11+2x
Hope everything is clear.
Let me know if you have any questions!
