Eight less than nine is one, and eight less than ten is two. Therefore, the numbers that are eight less than nine and ten are one and two, respectively.
x - 10 is the equation you would use to find the answer. Since you don't have a specific number to subtract from, you have to use x, and "ten less than" means that you have to subtract from your first number.
