Question

Which of the following equations is equivalent to 1/4x -1/2 y = 8?

A .2x - 4y = 8
B. 2x - 4y = 64
C. 4x - 2y = 64

Answer 1

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,

Answer 2

correct answer is b.

Explanation:

`1/4x-1/2y=8`

multiplying this equation to 8, we get

`8(1/4x-1/2y)=8(8)`

now, multiplying 8 to each term of the equation

`8(1/4x)-8(1/2y)=8(8)`

`2x-4y=64`

and we get the correct answer.
