Answer:
To Find the median you order them from least to greates or vice versa, therefore 4,5,6,6,12,17,19 the median would be 6 because it is in the middle, the mean would be adding all of them and dividing by 7 because there are 7 variables. therefore the mean is 9.85 or you can round to 10 / 9.9
6x-1=4x+6
subtracting 4x from each side
2x-1=6
adding 1 to each side
2x=7
divide by 2
x=7/2 or 3.5
check: 6(7/2) -1 =4(7/2)+6
21-1 =14+6
20=20 correct
