When finding the solution for an equation we get one answer for x. (There is only one number that satisfies the equation.) For 3x – 5 = 16, the only solution is x = 7. When we have an inequality to solve (greater than, less than, greater than or equal to, or less than or equal to) we have a range of numbers that can be a solution.
