Step-by-step explanation:

$2 {x}^{2} - 5xy + y \\ 2 \times {3}^{2} - 5 \times 3 \times - 4 + ( - 4) \\ 2 \times 9 - 15 \times - 4 - 4 \\ 18 + 60 - 4 \\ 78 - 4 \\ = 74$

Hope this helps you.

Can I have the brainliest please?

have a nice day!

He started with the number 32. You just have the do the opposite of the steps using the end result, 131 (131 MULTIPLIED by 2, instead of divided). Hope this helps.
