Hello from MrBillDoesMath!

Answer:

Choice B


Discussion:

Multiply the original equation by 8:

8  (  (1/4) x - (1/2) y )   = 8   * 8  =>

(8/4)x - (8/2)y = 64 =>

2x - 4y = 64


which is Choice B


Thank you,

MrB

Answer:

correct answer is b.

Step-by-step explanation:

[tex]1/4x-1/2y=8[/tex]

multiplying this equation to 8, we get

[tex]8(1/4x-1/2y)=8(8)[/tex]

now, multiplying 8 to each term of the equation

[tex]8(1/4x)-8(1/2y)=8(8)[/tex]

[tex]2x-4y=64[/tex]

and we get the correct answer.
