At the bottom!
Step-by-step explanation:
Put the two equations into the same standard form:
2x-y=8
-5x+2y=3
Now if you add the two equations up, guess what will happen?
You will "eliminate" the y variable, and only be left with the x variable.
Technically, you will get:
2x-y+2+28-5x+29+2y=8+23
-3x+20y=11
-3x=11
