Given:
.
(7x - 11)+(4x - 3)
.
Since both of the sets of parentheses are preceded by a + sign, you can remove the parentheses
without changing the signs of the terms inside of the parentheses. When you remove the
parentheses you have:
.
7x - 11 + 4x - 3
.
Now combine the like terms.
.
The terms containing an x are 7x and +4x. They both have + signs so when you combine them
you get +11x. And the terms that are just numbers are -11 and -3. They both have negative
signs so when you combine them you get -14. So the answer to this problem is:
.
+11x - 14
.
Answer a) is the correct answer.
.
Hope this helps you to understand the problem.
