Cy=x+
adol
y = 2


PLEASE HELP!!!!!

Answer 1

B

Explanation:

Given

5 - 2x + 7y = 4 ( subtract 5 from both sides )

- 2x + 7y = - 1 ( add 2x to both sides )

7y = 2x - 1 ( divide all terms by 7 )

y =
`(2)/(7)` x -
`(1)/(7)` → B

Answer 2

B.
`y=(2)/(7)x-(1)/(7)`

Explanation:

We have been given an equation
`5-2x+7y=4`. We are asked to choose the equation that is equivalent to our given equation.

We will convert our given equation in point-slope form of equation.

`5-2x+2x+7y=4+2x`

`5+7y=4+2x`

`5-5+7y=4-5+2x`

`7y=-1+2x`

`7y=2x-1`

Divide both sides by 7:

`(7y)/(7)=(2x)/(7)-(1)/(7)`

`y=(2)/(7)x-(1)/(7)`

Therefore, equation
`y=(2)/(7)x-(1)/(7)` is equivalent to our given equation and option B is the correct choice.
