Solving Equations

6.- Solving First degree equations

Watch these two videos (08 & 09) to beggin with simple equations. While watching, take notes in your notebook, Remember that ...

 This is because, as you have learnt, ...

👉Find here the tasksheet AL06 with some activities about solving equations. 👈 After watching the videos you will be able to do the ex: 19, 20 & 21.

👀  Video 08 teaches how to do A19 and Video 09 to A20 and A21

Here you have the lesson to learn how to solve equations with parenthesis.

Remember that when you find brackets in the equation, the first thing you have to do is to remove the brackets by applying the distributy property.

And now you are ready to do the activity A22 of the tasksheet AL6


Find the solutions to e) and n) in these to videos:

Do now this one and check the solution after. I will correct it next week:

Equations with denominators:

Equality and Equation. Algebra. Unit 6

5, 6.- Equations. Equivalent equations

Before studing and solving equations let us start by understanding what equations are and what is the solution of an equation.

And now what is and how to make equivalent equations:

After watching the videos make sure you understood the basics and are ready to go and solve real equations which is going to be the aim of our next videos.

👉 Task: Revise and complete your notes in your notebook, revise the corrected exercises and do again those that you are not sure how to do it.

Unit 6. Algebra. MONOMIALS

Within this post we are going to study the  third  and forth paragraphs of Unit 6.

3.- Monomials

Watch the video, if you missed the lessons copy the notes in your notebook, as you would do in class, and solve the exercises later




4.- Operations with monomials

This video explains what similar monomials or like monomials are and how to add or subtract monomials



Exercises about Monomials:  AL04 👈


This video  shows how to multiply, divide or opertate powers on monomials



And the exercises to practice the product, division and powers with Monomials: AL05👈

Unit 6. Algebra

UNIT 6         ALGEBRA

6. Solving first degree equations
   
7. Word porblems and exercises

Let us start with 1.- Algebraic expressions:

Start by watching this 9' video and learn what alegebraic expressions are and get ready to do the exercises. Copy the notes in your notebook so that you can consult in the case you need it later

2.- Numerical Value of an algebraic expression. Evaluating an algebraic expression.
