Video+3





 The title of the video is "Algebra I"
 * I. Before you watch the video answer the following questions **

I Think that this video will be about this Math's branch, basic knowledge about this.
 * What do you think this video will be about? **

Addittion, multiplication, division, common factor, algebraic expression !!
 * Mention five words you think you might listen to in the video **.

 Equations with one variable Equations with variables in both members Equations with multiples variables
 * 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 __**

The keys that he mentions for solving any equation are : - Use the inverse additive, that significate choose a opposite number , that is the same number but with opposite sign -Other key is use to multiplicative inverse, the reciprocal number , to simplify the equation
 * __ 2. What are the two keys he mentions for solving any equation? __**

First, he observe which variable has to clear, then he add +2 in one side to eliminate the number (-2) in the side where is the variable. Them he uses the reciprocal of (-1/5) on two sides and finally he clears the X, and get a result : X = -80
 * __ 3. a. Mention the steps he takes to solve the 1st problem. __**

Is an equation with a variable on one member with a fraction
 * __ b. What kind of equation is this one? __**

First, he observe which variable has to clear, then he applies the distributive property in one side, the he adds the inverse additive (-2) in the two sides and adds too, the variable X in one side of the equation, then he add the inverse additive of 4X in both sides and finally he uses the reciprocal (inverse multiplicative ) of 5X .. And get a result, X= -18/5 !!
 * __ 4. a. Mention the steps he takes to solve the 2nd problem __**

Is an equation with variables on both sides using the distributive property.
 * __ b. What kind of equation is this one? __**

First, he uses the inverse additive of (2L) on both sides to leave the variable W only in one side. Them, he multiply both sides for the reciprocal of 2 that is 1/2 and finally he clears the variable W and get a new result, W= P/2 -L
 * __ 5. a. Mention the steps he takes to solve the 3rd problem. __**

Equation with multiple variables for one of the variables
 * __ b. What kind of equation is this one? __**

First, he uses the reciprocal of 1/D in both sides. Then, he adds the inverse additive of C in both sides and finally the variable B was clear, and the result was B=AD -C
 * __ 6. a. Mention the steps he takes to solve the 4th problem. __**

Is an equation with multiple variables for one of the variables with a fraction
 * __ b. What kind of equation is this one? __**

The difference between the problem 3 and the problem 4, is that the problem 3 he used the inverse additive to clear, but in the problem 4, he used the reciprocal because the variable was a fraction
 * __ c. What’s the difference between problem 3 and problem 4? __**

Of course, the video is didactic and easy to understand.
