 * What does it mean to simplify? What does it mean to solve? What does it mean to evaluate? Write in complete sentences. You may use your book to help you. Please give an example of each.**


 * Simplify:**To simplify something means to complete the problem you are given.
 * Solve:** If you solve a problem, you are to find the answer.
 * Evaluate:**To evaluate means to substitute.

Walk me through the steps of evaluating the following: -2x + 3y, x=-2 y = -4. Please use complete sentence**s.
 * Walk me through the steps of simplifying the following expression: -2x + 12 - 3x + 4 - 3y. Please use complete sentences.

The first thing you need to do in this problem is to simplify, or combine like terms. So, you would do 2x-3x, and get 1x. Next, you do 1x-3y, and get -2. Then, you do -2+12, and get 10. Finally, you would do 10+4, and your final answer is 14!
 * -2x + 12 - 3x + 4 - 3y**

In this equation, you want to evaluate, or substitute the variables. That would give us "-2*-2+3*-4." First, you figure out -2*-2, which is 4. Next you do 3*-4 which is -12. Then you put those together, and get 4-12, which is -8!
 * -2x + 3y, x=-2 y = -4.**
