Using the method of elimination. multiply the top equation by -3..

-3(8x+2y=64) >>                    -24x-6y=-192

rewrite the bottom equation >> x + 6y=32

add both equations together (straight down).. -23x=-160  (the y-variables cancel)

divide both sides by -23 ... x ~ 7.0

plug x back into either original equation (i chose the bottom)..

7.0 +6y=32

subtract 7.0 from both sides.. 6y =25

divide both sides by 6.. y~4.2

the solution is the ordered pair (7.0,4.2) **estimated
