What you need to know:
Linear equations are the sorts of equations that appear in many, many differential mathematical problems. They can look very simple like x + 2 = 5, or they can look a little more complicated, such as:
5p - 7 = 3p + 3
The golden rule when solving these equations (and indeed, equations of all kinds) is that whenever you apply some operation to one side of the equation (add 5 to it, multiply it by 3 etc), you must also do the same thing to the other side. The aim should be to collect terms of the same type together on the same side of the equals sign, a process known as collecting like terms. You should be able to perform operations to the equation above to put all your terms involving p on one side, and all your constant terms are on the other. The aim of this process is to obtain p = something, so always have that as your aim. You will certainly be asked to solve linear equations like these in your exams, so you should become very familiar with them.
