and 

Example Question #19 : Simplifying Equations

Simplify the expression by combining like terms.

Simplify: 

Possible Answers:

Correct answer:

Explanation:

The original equation:

Now move all terms to one side, in this example, we will use the right side, but either side will work.

 

       

As you can see, we subtracted the terms on the left from both sides, effectively moving them to the other side.

 

Regrouping the terms so that "like terms" are together. Like terms are defined by having the same power of x.

 

 

Now, we add any terms that have like powers of x.

Now that all terms have been combined, we are finished. The equation is simplified.
