Hi there!
Let's simplify step by step.


[tex]2y(3 - x) + 7(x - 2y) = [/tex]
First we work out the parenthesis (for instance possible by using rainbow technique).

[tex] 2y \times 3 + 2y \times - x + 7 \times x + 7 \times - 2y = \\ 6y - 2xy + 7x - 14y = [/tex]
Finally we collect the common terms.

[tex] - 2xy + 7x - 8y[/tex]
~ Hope this helps you!
The first step for solving this expression is to distribute 2y through the first parenthesis.
6y - 2xy + 7(x - 2y) 
Now distribute 7 through the second set of parenthesis.
6y - 2xy + 7x - 14y
Lastly,, collect the like terms with y.
-8y - 2xy + 7x
Since we cannot simplify any further,, -8y - 2xy + 7x is the correct answer to your question.
Let me know if you have any further questions.
