3x + 6y = 18
2x + 5y = 20
explain, in complete sentences, how u would use the graphing method to solve the following system of equations.

i know what to do, i just don't know how to explain it.

You graph it. Then circle where they intersect and write. "here is the solution" http://www.google.com/imgres?um=1&hl=en&sa=N&biw=1049&bih=941&authuser=0&tbm=isch&tbnid=LIYStgvKYShV0M:&imgrefurl=http://mozey.wordpress.com/2007/02/18/funny-exam-answers/&docid=KWLUOoQGqifSeM&imgurl=http://mozey.files.wordpress.com/2007/02/findx.gif&w=342&h=240&ei=oxKaT52lDeSY2wWz59TsDg&zoom=1&iact=hc&vpx=260&vpy=156&dur=631&hovh=188&hovw=268&tx=164&ty=93&sig=107907455760490705585&page=1&tbnh=141&tbnw=199&start=0&ndsp=25&ved=1t:429,r:1,s:0,i:72

1. Rearrange both equations into slope intercept form
         y=0.5x+3
         y=0.4x+4
2. Graph both equations on the same x-y plane.
3. At the point where both graphs intersect each other is the solution of the system of equations.
