Example Question #2 : How To Subtract Variables
Simplify:
Remember, when there is a subtraction outside of a group, you should add the opposite of each member. That is:
That is a bit confusing, so let's simplify. When you add a negative, you subtract:
Now, group your like variables:
Finally, perform the subtractions and get:
Example Question #2 : How To Subtract Variables
Simplify:
Begin by rewriting the subtracted group as a set of added negative numbers:
Now, simplify that a little by rewriting the additions of negatives as being mere subtractions:
Next, move the like terms next to each other:
Finally, combine like terms:
Example Question #102 : Algebraic Concepts
Simplify:
You need to begin by distributing the minus sign through the whole group 
Simplifying the double negative, you get:
Now, you can move the like terms next to each other:
Finally, simplify:
Example Question #3 : How To Subtract Variables
Simplify:
This problem is as simple as it appears. All that you need to do is group together like terms:
The only like terms are the 
Example Question #4 : 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 #7 : How To Subtract Variables
Simplify:
Begin by distributing the subtraction through the parentheses:
Next, group the like terms:
Now, combine them:
Example Question #11 : How To Subtract Variables
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:
Example Question #701 : Concepts
Simplify:
Begin by distributing the subtraction through the group:
Next, change the double negative to a positive:
Example Question #2 : Apply Properties Of Operations To Expand Linear Expressions With Rational Coefficients: Ccss.Math.Content.7.Ee.A.1
Simplify:
Begin by distributing the 
Multiply each factor:
Change the double negation to addition:
Combine like terms:
Example Question #7 : Expressions & Equations
Simplify:
Begin by distributing the 
Multiply all factors:
Group together the only like factor (
