How do I solve an equation?


There are basically two ways of solving an equation. We'll use a couple of examples to show the two different methods.

Solving an equation basically means you're working out what the unknown value is. So, if we were solving the equation 3d + 17 = 64 then we would be trying to work out what number, the letter d represented.

The first method of solving equations involves performing an identical action to both sides of the equation, in other words, to both sides of the equals sign.

So, say we have the equation ...


Let's try another example ...



Let's solve the following equation ...
