Video 3: "Algebra I"
I. Before you watch the video answer the following questions. The title of the video is "Algebra I" What do you think this video will be about? I think it would be about algebra 1 classes and themes that are treated on this asignature

Mention five words you think you might listen to in the video.

linear, congruence, equation, solution, theorems

II. Now click on the following link and watch the video. While watching, please answer the following questions:

1. Mr. Mc Call is solving three types of equations in this video. Which are those types of equations? **??????????** 2. What are the two keys he mentions for solving any equation? the additive inverse and the reciprocal

3. a. Mention the steps he takes to solve the 1st problem. 1- first he used the additive inverse to eliminate the negative two 2- then he used the reciprocal o eliminate the negative 5 3- and then he resolve the operations and find the answer

b. What kind of equation is this one?

An equation with a variable on one side with a fraction

4. a. Mention the steps he takes to solve the 2nd problem.

1- First he multiple the terms in the right side of the equation using the distributive property 2-then he uses the additive inverse to eliminite the four x 3-then he uses the negative inverse of negative two 4-then he uses the reciprocal of five to finnaly get the answer

b. What kind of equation is this one?

An equation with variables on both sides

5. a. Mention the steps he takes to solve the 3rd problem.

1-First he uses the negative inverse of two l 2- then he uses the reciprocal of two, then he get **S** to the answer

b. What kind of equation is this one?

An equation with multiple var **i** ables for one of the variables

6. a. Mention the steps he takes to solve the 4th problem.

1-First he uses the reciprocal of d to eliminate the d 2- then he uses the additive inverse of c to eliminate the c on the right side of the equation and then he get **S** the answer

b. What kind of equation is this one?

An equation with multiple variables on both sides

c. What’s the difference between problem 3 and problem 4? **??????????????** 7. Did you like the video?

Yes it makes look algebra easy 8. What new things did you learn?

Not already much, but i did learn that the equations with multiple variables on both sides are the ones of much geometr__y__**ical** figures and if we learn to use s them we could solve alot of geometrical problems
