In the last basketball game of the season, paresh scored 2x points, teeto scored x+5 points, matt scored 3x+1 points, and lang-li scored 4x-7 points, x and jamel scored 2x-2 points. represent the tatal points scored by these five players.

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!
