324 times z, reduced by 12 is z.
Take this algebraic expression in pieces:
324 times z means we multiply 324 by the variable z.
324z
Reduced by 12 means we subtract 12 from 324z
324z - 12
The word is means we have an equation, so we set 324z - 12 equal to z
324z - 12 = z <-- This is our algebraic expression
