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?

I got the answer -x - 12y.. so.. B would equal -12. Right? xD

Answer 1

-x -4y is what i get

Answer 2

(x - 8y) - (2x - 4y)

x - 8y - 2x + 4y <--- This is where you made the mistake

Answer 3

\(\Large \color{Black}{\Rightarrow x - 8y - 2x + 4y }\)
