Question

In the below system, solve for y in the first equation.

x − 3y = −6
2x − 7y = 10
A. 1/3x+2
B. -1/3x+6
C. -x+2
D. -1/3x+2

Answer 1

The correct answer should be A.

Answer 2

The answer is the option A

`y=(1/3)x+2`

Explanation:

we have

`x-3y=-6` -----> first equation

`2x-7y=10` -----> second equation

Solve for y in the first equation

That means------> isolate the variable y in the first equation

`x-3y=-6`

`3y=x+6`

Divide by
`3` both sides

`y=(x+6)/3`

`y=(1/3)x+2`
