yeah y= 6 ..!

anonymous · Answer

(y + 2y + 3y) / 3 = (6y) / 3 = 2y
This is 12. Divide by two to get the result y = 6.

Ok, average is another name for the mean of the data set...
So y + 2y + 3y = 12
When you find the average (mean) you, in the end, divide by the number of numbers in the data set...3
12 * 3 = 36
So, y + 2y + 3y actually equals 36
Now we solve the equation...
6y = 36 (after combining like terms)

6.       6
-----------
Y = 6
Hope I helped (^_^)
