The X score is for a score x is
x μ σ
where μ is the mean and σ is the standard deviation. If " x is above the mean by ten points", that indicates that x μ = 10.

The z score is the number of standard deviations from the mean. You are already given the difference from the mean, so you can skip the usual step of subtracting from the mean.
