Question

Simplify each algebraic expression by combining like terms.
2x+ (9+x) -6

Answer 1

Answer:3x+3

Explanation:

First we remove the parenthesis because they are not needed in an addition problem to make it 2x+9+x-6

Then we sort and combine like terms, [2x+x]+[9-6]

After that, you add the coefficients of the the first term, which makes 3x and subtract 6 from 9 to get 3

This then leads you to 3x+3

Answer 2

3x +3

Explanation:

You want to simplify 2x+ (9+x) -6.

Like terms

Like terms have the same constellation of variables. Here, there are terms containing x, and terms not containing x.

2x+ (9+x) -6 = (2 +1)x +(9 -6) = 3x +3

The simplified expression is 3x +3.
