Example Question #5 : How To Subtract Variables
Simplify:
First, start by distributing the subtraction through the terms in parentheses. Note that you will be subtracting negative numbers:
Subtracting a negative is the same as adding a positive:
Now, group the like terms:
All you need to do now is combine like terms:
Example Question #701 : Concepts
Simplify:
Begin by distributing the subtraction through the parentheses:
Next, group the like terms:
Now, combine them:
Example Question #91 : Algebra
Simplify:
Begin by putting similar variables together. Remember that combinations of variables such as 
Combine like terms:
You can then rearrange the variables to get the answer as written:
