Maths - Solving eqations

In an equation, letters stand for a missing number. To solve an equation, find the values of missing numbers. A typical exam question is:

Solve the equation 2a + 3 = 7

This means we need to find the value of a. The answer is a = 2

Now you've got the hang of simple equations, let's look at some slightly trickier ones.

Sometimes an equation will have multiples of an unknown - eg 3x = 12, 5b = 20 or 16y = 4

To solve these, you need to get the unknown on its own. Do this by dividing both sides.
