Solving Equations 1….2…..3
Introduction: Welcome to Solve Equations in a 1...2...3. In this Webquest you are going to learn how to solve equations easily without getting a headache. Don't worry about not understanding some steps because not all people learn at the same pace. You are allowed to look back at the process every time you want.

TASK: Your task will be to solve 20 equations. You will also be required to make 5 equations of your own with the answer. Those equations will be given to a partner who will solve and correct them (if there is a mistake). One more thing will be expected from you and it will not be hard. You are expected to help a classmate or partner (if you are in school or are assigned with one) if he does not comprehend a step or if he gets an answer wrong. I do not mean to give him the answer because then he or she will not learn. The materials you will need are the following: Please take notes on the videos and/or websites Sample Problem: -6+N=15 1.-You see you have a negative integer. So you have to add 6 to -6+N=15 to make -6 //disappear from the left side.// Remember that if you add 6 to the left side you have to add it to 15 too. -6 + N = 15 -6 + 6 + N = 15 + 6

 * 2) A pencil
 * 3) An eraser
 * 4) A notebook

N = 21

Your answer should be 21. So N=21!
 * Remember an equation is a problem whose both sides are the SAME

Here is another explanation: _ -21 -20 -19 -18 -17 -16 -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 You have a number line. Now go to -6 and add 6 to the right. The answer you should get is 0. Now go to 15 and add 6 to the right. Your answer should be 21.
