Given the following expression:
[tex]2y(x-4)[/tex]And knowing that the value of "x" is:
[tex]x=6[/tex]And the value of "y" is:
[tex]y=9[/tex]You can substitute those values into the expression, as following:
[tex]2y(x-4)=2(9)(6-4)[/tex]In order to evaluate it, you need to folow these steps:
- Solve the subraction inside the parentheses.
[tex]=2(9)(2)[/tex]- Finally, find the product solving the multiplication (remember that the Product is the result of a multiplication).
Then, you get that the answer is:
[tex]=36[/tex]
