SOLVING SYSTEMS OF EQUATIONS BY ELIMINATION

In this video the Professor Von Schmohawk explain how to solve a system of equations using
the elimination method.

If you want to know more about the elimination method, you should see this another video:

THE TORTOISE AND THE HARE

Today we have begun a new unit about systems of linear equations with a new version of the famous fable about the race between the tortoise and the hare. Here you are the video:

Solving Motion Problems with Linear Equations

In this video you will find the examples 4 and 5:

SOLVING PROBLEMS USING EQUATIONS

In this video you can find the examples 1 and 2 we saw in class this morning:

You have to do the example 3 as homework. This example is in the minute 6:21 of the following video, but you can go to it directly clicking in this link:

Solving an equation

This morning we watched this video in class:

Central Park

We are going to start the new unit in a different way:

Revision for the exam

These few next days we are going to do several exercises in order to revise the contents of this unit:

P. 52: 4, 6 a, c; 8, 10 (d, e, f), 11 (d, e, f), 13, 14. 
P. 53: 19, 20 a, b; 22 a, d; 24 a, b; 28.

P. 49: 1, 2.

P. 52: 6 b, d; 9, 12 (d, e, f). 
P. 53:17, 18, 20 c, d; 24 c, d;
P. 54: 30, 31, 33. 

And here you are the evaluation criteria sheet. It will help you to  check what you have to know about this unit.
