18 = 3 x 6 (six).
-6x/-6=18/-6 x=-3
3x=18 x=18/3 x=6
The answer is three. 6 x 3 = 18
3 x 6
1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
1 x 18 = 2 x 9 = 3 x 6 = 18
y = 6 x 3.5; If you can't do that in your head, split it up: 6 x 3 = 18, 6 x .5 = 3, 18 + 3 = 21
6 x 3
X = 1/3 since 6 is one third of 18.
1 x 18, 2 x 9, 3 x 6.
