You can put this solution on YOUR website!
6x +5y = 1
\n" ); document.write( "x = 11 -3y
\n" ); document.write( ".
\n" ); document.write( "substitute x = 11-3y
\n" ); document.write( ".
\n" ); document.write( "6(11-3y) +5y = 1
\n" ); document.write( "66 -18y +5y = 1
\n" ); document.write( "-13y = -65
\n" ); document.write( "y = 5
\n" ); document.write( ".
\n" ); document.write( "substitute y=5 into the first equation
\n" ); document.write( ".
\n" ); document.write( "6x + 5(5) = 1
\n" ); document.write( "6x = -24
\n" ); document.write( "x = -4
\n" ); document.write( ".
\n" ); document.write( "check answer by substituting into the second equation
\n" ); document.write( ".
\n" ); document.write( "11-3y = 11-15 = -4
\n" ); document.write( "x = -4
\n" ); document.write( "correct.
\n" ); document.write( ".
\n" ); document.write( "Answer: x=-4, y=5
\n" ); document.write( ".
\n" ); document.write( "Done. \n" ); document.write( "

\n" );
