It should be:
To solve an equation, you must apply the variable to one side of the equation.
This makes sense to me, but I'm not 100% positive.
z = (x - μ)/σ
Substituting given values, you have
3.6 = (x - 132)/20
(20)(3.6) = x - 132 . . . . multiply by 20
72 + 132 = x . . . . . . . . .add 132
204 = x
The value that has a z-score of 3.6 is 204.
