Determine the value of y for the system of equations.

x − 3y = 4
2x + y = 8

anonymous · Answer

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.

"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 :)
