If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
Z + 11 = 35 > Z = 24 Z - 11 = 35 > Z = 46

In the algebraic expression above z is an unknown variable.
Well, 'x' is equal to 'z'. Back in plane geometry, there was a mantra that said: "Two quantities equal to the same quantity are equal to each other." This question is an example of that mantra. So for Example: If x = 10 Then x = y (making y = 10) y = z (making z = 10) therefore z is the same.
