Example Question #83 : Algebra

Simplify:

Possible Answers:

Correct answer:

Explanation:

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 #1 : Apply Properties Of Operations To Expand Linear Expressions With Rational Coefficients: Ccss.Math.Content.7.Ee.A.1

Simplify:

Possible Answers:

Correct answer:

Explanation:

You need to begin by distributing the minus sign through the whole group .  This gives you:

Simplifying the double negative, you get:

Now, you can move the like terms next to each other:

Finally, simplify:

Example Question #102 : Variables

Simplify:

Possible Answers:

Correct answer:

Explanation:

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  terms.  Therefore, the simple answer is a matter of subtracting 3 from 4:

Example Question #81 : Variables
