An example of a pair of simultaneous equations is as follows:
4x + 3y = 10    (1) and
2x - 3y = 14    (2)
Now to solve these equations we can simply add them and solve for x, then sub that ...

Factorising equations:

Lets look at the example:   Factorise 3x+21 

In order to factorise this equation, we need to find a common factor of both 3x and 21. ...

The area of a triangle is the (1/2) x (base x the height).

Used for right angled triangles where c is the hypothenuse and a and b are the two other sides.

Equation: a² + b² = c²

Label the sides of th...
