Answer:

The answer is the option A

[tex]y=(1/3)x+2[/tex]

Step-by-step explanation:

we have

[tex]x-3y=-6[/tex] -----> first equation

[tex]2x-7y=10[/tex] -----> second equation

Solve for y in the first equation

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

[tex]x-3y=-6[/tex]

[tex]3y=x+6[/tex]

Divide by [tex]3[/tex] both sides

[tex]y=(x+6)/3[/tex]

[tex]y=(1/3)x+2[/tex]
