Elimination is another word for canceling out, this usually occurs in equations. This also occurs when you are trying to figure out the points of a graph
Take a look of this picture of an equation that deals with elimination:
2x+3y=20
-2x+y=4
_________
0+4y=20
4y=24
y=6.
Cancel the numbers out to get the variable by itself, in order to get the variable by itself you need to divide.
Hope this helped :)
Have a great day
