TO KNOW MORE ABOUT EQUATIONS SYSTEMS AND ITS APLICATIONS , LET´S HAVE A LOOK AT THIS GEOGEBRA EXERCISE AND MOVE THE BUTTONS:
During this course 2011 - 2012 MATHEMATICS is being taught for 4º ESO.
7 / 3 / 12 GRAPHING LINEAR EQUATIONS IN TWO VARIABLES
In order to learn how to draw linear equations in two variables:
21 / 2 / 12 STUDENTS' EXERCISES

These are some of your exercises using a spreadsheet program:
Change the values for a, b and c in the quadratic equation ax2+bx+c=0.
You´ll see the real solutions for x, straightaway.

Our next step will be to include logarithms and trigonometric functions in our very well known one-variable equations.
Can you solve this equation?
log(x+21)+logx=2
