So what you're doing is you're combining
2x + x + 5 + 3x + 1 + 4x - 7 + x + 2x - 2.
What you need to do is combine like terms.
2x, x, 3x, 4x, x, and 2x are all like terms.
(x is the same as 1x)
2x + x + 3x + 4x + x +2x = 13x.
Now combine the constants.
+5, +1, -7, and -2 are the constants.
(Make sure to include the signs)
5 + 1 - 7 - 2 = -3
So you're final answer should be 13x - 3.
This is as simplified as it can get, and it's in standard form.
Hope this helped!
