Question

Simplify the following expression: (x - 8y) - (2x - 4y). If the final answer is written in the form Ax + By, what is the value of B?

Answer 1

x - 8y - (2x - 4y) =
x - 8y -2x + 4y =
-1x - 4y........B = -4

Answer 2

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 $-4$.
