Answer:
Step-by-step explanation:
The given expression is:
[tex](x-8y)-(2x-4y)[/tex]
Simplifying the above given expression, we get
[tex]x-8y-2x-4y[/tex]
[tex]x-2x-8y+4y[/tex]
[tex]-x-4y[/tex]
which is the required simplified form.
Now, comparing the above simplified form of the expression with [tex]Ax+By[/tex], we get
[tex]A=-1[/tex] and [tex]B=-4[/tex]
Therefore, the value of B is [tex]-4[/tex].
