Question

Help!

Determine the value of y for the system of equations.

x − 3y = 4
2x + y = 8

Answer 1

I'd cancel x and get

-2x + 6 = -8
2x + y = 8 (Upon multiplying by -2)

7x = 0
x = 7, but that's not one of my answers.

Answer 2

Answer 6

"I'd cancel x and get <-----correct

-2x + 6y = -8 <----NOTE
2x + y = 8 (Upon multiplying by -2) "

now ADD those 2 equations...
-2x+2x+6y+y = -8+8
you can get y from here easily :)
