Suppose the number is x. Then x2 + 12 = 7x So that x2 - 7x + 12 = 0 ie (x - 3)(x - 4) = 0 So the two possible solutions are x = 3 and x = 4

Twelve times seven equals 84.
The question is ambiguous and the two possible answers are: Twelve times (a number and 5 times the number) = 12*(n + 5n) = 12*6n = 72n Twelve times a number amd five times the number = 12*n + 5*n = 17*n
