For example: Given the equation m + 5 = 8, m = 3 is the solution since 3 + 5 = 8. Given the equation k^{2} = 36, k = 6 and k = 6 are the solutions since 6^{2} = 36 and (6)^{2} = 36. Given the equation x + y = 12, (2,10), (4,8), and (7,5) are just some of the solutions in a whole set of solutions for this equation, since 2 + 10 = 12, and 4 + 8 = 12, and 7 + 5 = 12.
