Get all the values of the histogram and put them in order:
For example 2,5,7,1,7,3 becomes 1,2,3,5,7,7 and then you get the middle number, which is in this case (3+5)/2=3.5
Then see which of the readings lie on 3.5.
Step-by-step explanation:
Find the common like terns in each expression!

+3y -2y = 1y or y
Then sort by the greatest values:
5z+2x+1y
