Let "the number" be x. Start with the following equation: x2 + 7 = 8x Move the 8x to the left side of the equation and set it equal to zero: x2 - 8x + 7 = 0 Factor the left side of the equation: (x - 7)(x - 1) = 0 Now you have two equations: x - 7 = 0 and x - 1 = 0 Solving these equations, you will get this: x = 7 and x = 1. This means that either 1 or 7 can be placed into this equation to make it true. 12 + 7 = 8(1) and 72 + 7 = 8(7)
