As per the given problem, 'x' represents Casey's weekly salary.
Given that Sydney made $33 less than twice Casey's weekly salary.
Consider the following,
[tex]\begin{gathered} \text{Casey's weekly salary}=x \\ \text{ Twice of Casey's weekly salary}=2x \end{gathered}[/tex]
Then, Sydney's salary is calculated as,
[tex]=2x-33[/tex]
Thus, Sydney's weekly salary can be represented by the expression,
[tex]2x-33[/tex]
