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? About how to solve and equation with unknown numbers. Mention five words you think you might listen to in the video. Plus, equations, equal, divided, minus

Correct ! !
II. Now click on the following link and watch the video. While watching, please answer the following questions: [] Image taken from: [] on August 12th. 2009

1. Mr. Mc Call is solving three types of equations in this video. Which are those types of equations? equations with 1 variable, variables in each side of the equation, more than 1 variable in the same equation 2. What are the two keys he mentions for solving any equation? The Additive invert, and the reciprocal. 3. a. Mention the steps he takes to solve the 1st problem. First he finds the variable, then he use the additive invert to eliminate the minus two in the right side of the equation, then he use the reciprocal to eliminate the number five that is dividing the variable, doing this, he multiplicates by minus five divided by 1 in each side of the equation, and the variable is alone in the right side of the equation and the result is in the other side. b. What kind of equation is this one? Is an equation with one variable in only one side of the equation

Capitalize and you forgot the subjetc (what subjetcs xD?)
4. a. Mention the steps he takes to solve the 2nd problem. He uses the distributive property in the right side of the equation to eliminate that multiplication, then he regroups the variable x in the left side of the equation adding 3x to 6x, that is equal to 9x, then he passes the positive 4x to the other side of the equation using the additive invert, and eliminates the plus two in the left side using again the additive invert, after all this steps there are only 5x in the left side and minus 20 in the other side, so he use the reciprocal to eliminate the 5 that is multiplying the variable, and the variable is alone in the left side of the equation and the result is in the right side. b. What kind of equation is this one? An equation with one variable but in both sides of the equation. 5. a. Mention the steps he takes to solve the 3rd problem. He identif y **(Whats wrong here?)** the variable "w", and uses the additive invert to eliminate the plus 2L on the right, then he use the reciprocal to eliminate the 2 that is multiplying the w, then he find the variable "w" alone in the right side and the result on the other side. b. What kind of equation is this one? An equation with more than one variable for one of the variables. 6. a. Mention the steps he takes to solve the 4th problem. He uses the reciprocal to eliminate d in the right side of the equation multiplying d in each side of the equation, then he use ** S ** the additive invert to eliminate the c in the right side of the equation adding "minus c" in each of the equation, then the equation is resolved. b. What kind of equation is this one? An equation with more than one variable for one variable but this time there is a fraction. c. What’s the difference between problem 3 and problem 4? 7. Did you like the video? Not realy,I dont like math. 8. What new things did you learn? Nothing new but I remembered a lot of properties
