5x+6y=23
4x-6y=-14

I've tried it:
5x+6y=23
-
4x-6y= -14
_______________

x = 37

Then I did this:

5(37)+6y=23

185+6y=23
-185 -185

6y=-162
--- ----
6 6

y = -27

But when I plug those numbers in, it doesn't work. Help please

P.S.: I am not looking for the answer, but for the way of answering this question. Thank you

you forgot that 6y - (-6y) = 12y. so it would be:

5x+6y=23
-
4x-6y= -14
----------------
x + 12y = 37

instead, try adding the equations together
5x+6y=23
+
4x-6y= -14
---------------
9x + 0 = 9
