First take the 4x - the two numbers that will be +/- to the x in the brackets will need to add to form this number, so the possibilities are 1 and 3 or 2 and 2.Now take the 3 - the two nu...

I will use the whiteboard in order to explain the answer to my question. The format will follow:Understanding what it means to 'solve' one equationUnderstanding what it means to 'solve' two equationsVaria...

4x - 3y = 11 10x + 2y = -1 x2 x38x - 6y = 22 30x + 6y = -338x = 19x = 28 - 3y = 11-3 = 3yy = -1x=2, y=-1

You want to express this expression in the form (x+a)(x+b) to do this you want to find two numbers that add to make -5 (the coefficient of x) and multiply to make 6. Let's first focus on numbers that mult...

Working with more than 2 variables in simultaneous equations can be daunting at first, but as long as you apply the same methods you have learned for simpler problems, you will get used to these more comp...
