For periods B, F, and G - Simplifying Variable Expressions

Ex. you have the following variable expression:

5x + (-2) - 7x + 3 + x

What are the terms?
5x,-2,-7x,3,x

What are the like terms?
First set --> 5x,-7x,x
Second set --> -2,3

What are the constant terms?
-2,3

What are the coefficients? (the number part of a variable term)
5,-7,1

How would I simplify:
5x + (-2) - 7x +3 + x

First change the expression to all addition:
5x + (-2) + (-7x) + 3 + x

Next combine like terms, in this case I'll combine the variable terms first:
-x + (-2) + 3

Then I'll combine my constant terms:
-x + 1

So I've simplified 5x + (-2) - 7x + 3 + x to -x + 1
