Elimination would involve multiplying whole equations by 11 or 17
\n" ); document.write( "Graphing is not accurate
\n" ); document.write( "So I would solve by substitution.
\n" ); document.write( "x = 25/6, y = 17/6\r
\n" ); document.write( "\n" ); document.write( "11x + 17y = 94
\n" ); document.write( " x + y = 7
\n" ); document.write( "x=7-y
\n" ); document.write( "11(7-y) + 17y = 94
\n" ); document.write( "77-11y+17y=94
\n" ); document.write( "6y=17
\n" ); document.write( "y=17/6
\n" ); document.write( "x + y = 7
\n" ); document.write( "x + 17/6 = 7
\n" ); document.write( "x=(42-17)/6
\n" ); document.write( "x=25/6\r
\n" ); document.write( "
