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