First, let's find the additive inverse of the linear expression within the second set of parentheses. To do so, we can distribute -1 into the second set of parentheses. When we do so, we multiply each term of that linear expression by -1.
Now, let's identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined.
( 3x+ 4)+( - x - 2 )
In this case, we have two x-terms and two constants. Let's arrange the like terms in columns. Then, let's perform the addition.
3 x +4&
(+) - x -2&
2 x +2&
Therefore, we get the following result.
(3x+4)-(x+2) =2x+2
