es
A)
y = 2x - 5
B)
y = 2x + 5
)
y= {x+5
yox=20
D)

Answer 1

Option B

Explanation:

-8x + 4y = 20

`-8x+8x+4y=20+8x \leftarrow \text {Addition Property of Equality.}\\4y=20+8x\\\\(4y)/(4)=(20+8x)/(4) \leftarrow \text {Division Property of Equality.}\\y=5+2x\\\boxed {y=2x+5}`

Option B should be the correct answer.

Answer 2

Explanation:

4y = 20 + 8x

y = 5 + 2x
