Answer:
-7y + 8x
Step-by-step explanation:
The given expression is
[tex](-4y-x)-(3y-9x)[/tex]
To find the equivalent expression, we have to reduce like terms as follows
[tex](-4y-x)-(3y-9x)\\-4y-x-3y+9x\\-4y-3y-x+9x\\-y(4+3)-x(1-9x)\\-7y+8x[/tex]
So, the equivalent expression is
[tex](-4y-x)-(3y-9x)=-7y+8x[/tex]
Therefore, among the options, the right choice is the second one.
