18-3
18
well the product of 6 and 3 is 18 18-5 is 13
6 x 4 = 24 24 - 6 = 18
81=18*4.5

"The sum of a number and three times another number is 18. find the numbers if their product is a maximum?"
12 or 18
the number is 18
most likely 18
18 = 1x18, 18 = 2x9, and 18 = 3x6
12 and 18 have three factor pairs.
2x - 16 = 3x/18
well the product of 6 and 3 is 18 18-5 is 13
6 x 4 = 24 24 - 6 = 18
18 times three is 54.
