May someone me with this math problem, you

Ok so you add 3x and 6x to get 9x, and your equation would be 9x-2=25

First arrange the data in ascending order:-

60, 60, 62, 63, 63, 63, 64, 65, 66, 71, 74, 79,  82, 83, 84, 85, 86, 88, 88, 89, 93, 99

The mode is the value which occurs the most Here it is 63

The median is the middle number in the list ( or the mean of the 2 middle numbers)  =    (74+79) / 2 =  76.5

To find the mean add up the total and divide by the total number of data which is 22
