    x^2 - 9 = 45 bring the numbers to one side x^2 = 45 + 9 (when you bring a number to the other side it changes to the opposite sign e.g. negative to positive) x^2 = 54 to get x by it self you need to square root it, but remember whatever you do to one side you also do to the other side so you square root 54 as well and you have the answer for x
