I hope the expression is 5x² - y.
To evaluate the value of above expression for x = 4 and y = 24, substitute these values in the above expression. Therefore,
5x² - y = 5 (4)² - 24
= 5 * 16 - 24
= 80 - 24
= 56.
Hope this is your question, if not I think you will, still be able to
find an answer of your question based on this solution.
Hope this helps you!
