Finally, we get to the whole point of algebra.
You are given some text and you have to create an equation and then solve it. Sometimes you can work the easy answers out in your head, but you must write out the equation. That way you practice the technique and develop the skills to work out tougher problems also.
The work for the long weekend included these 2 questions:
p386 - q4 (make sure you only use a single unknown)
p389 - q1 (simultaneous equations)
and I also want you to try to solve the third type of problem you can enounter
p394 - q3 (this is solved using a quadratic equation)
We will look at each of these as well as a much trickier problem of the 3rd type (quadratics) tomorrow.
