This video covers how to solve simultaneous equations. This is where you have two equations that both have 2 unknown variables, like the equations 2a + b = 5 and 3a + 2b = 9. The only way to solve these and find the missing variables (a...

This video explains how to find the coordinates of a point that lies a certain ratio along a line, e.g. "If A is (3, 4) and B is (-7, 8), and C lies somewhere on the line AB such that AC : CB is 3 : 1, what are the coordinates of C?". We...

This video covers how to solve linear simultaneous equations using graphs. One way to solve simultaneous equations is by plotting them both on a graph and finding the point where they cross. The coordinates of this point will be the...

This video covers how to solve harder algebraic equations, which only have variable on both sides of the equation and multiple operations. For example 2x + 3 = 5x - 9 This is part 3 of our 3 part series on solving algebraic equations....

This video covers how to rationalise the denominator of a surd, which just means to get rid of any surds on the bottom of a fraction. This is part 3 of our 3 part series on surds. This video is suitable for maths courses around the...
