solve by the elimination method,9x-y=71 x+8y=16
You add the like terms together and the y's get "eliminated" making it
Plug x into one of the original equations (either one it will give you the same answer)
x=8 y=1 or (8,1) is the final answer.
multiply x+8y=16 by 9 which is 9x+72y=144then you get y=1 after equation worksub y=1 into equation x+8y=16then you get x=8
