Here we have the following expression:

We combine like terms in order to simplify expression. To do so, we combine terms with the same variable and exponents. In this exercise, let's apply distributive property first:

Its a bit long to describe here but the following link will show you how:-

19% of the voters were in Favor of building the shopping center.
<u>Step-by-step explanation</u>:
- Number of votes in favor of the shopping center = 4,000
- Number of votes against the shopping center = 17,000
Total voters in the city = number of votes in favor of the shopping center + number of votes against the shopping center.
- Total voters = 4000 + 17,000 = 21,000.
Percentage= (No. of votes in favor of shopping center / total voters)
100
⇒ (4000/21,000)
100
⇒ (4/21)
100
⇒ 19%
∴ 19% of the voters were in Favor of building the shopping center.
Like terms are terms that are the exact same excluding coefficients.
To combine like terms, add or subtract the coefficients.
Here are a few examples.
-3x^2+ 2x^2= -x^2
14xyz-12xyz=2xyz
12p-3p+8p= 17p
