What's that over there in the second equation, a plus?

anonymous · Answer

3x + 2y = 11
  x - 2 = 4y
srry everyone

Okay, first thing to do is to observe, you clearly see that the second equation is easier, so you isolate the x down there...

x = 4y+2.
Now plug this thing in the first one...
3(4y+2) +2y = 11 => 12y +6 +2y = 11 => 14y = 5 =>
 y = 5/14
x = 24/7

Weird it doesn't match with any of the possible answers though, you sure you wrote it correctly?
