p+6q=11
\n" ); document.write( "4p-q=-6
\n" ); document.write( "solve 2nd for q
\n" ); document.write( "add 6 to both sides
\n" ); document.write( "add q to both sides
\n" ); document.write( "4p+6=q
\n" ); document.write( "substitute q in first
\n" ); document.write( "p +6 *(4p+6)=11
\n" ); document.write( "p +24p+36=11
\n" ); document.write( "combine
\n" ); document.write( "25p=-25
\n" ); document.write( "p=-1
\n" ); document.write( "substitute p in first
\n" ); document.write( "-1+6q=11
\n" ); document.write( "add 1 to both sides
\n" ); document.write( "6q=12
\n" ); document.write( "q=2\r
\n" ); document.write( "\n" ); document.write( "check
\n" ); document.write( "4p-q=-6
\n" ); document.write( "plug in p and q\r
\n" ); document.write( "\n" ); document.write( "4(-1)-(2)=-6
\n" ); document.write( "-4-2=-6
\n" ); document.write( "-6=-6
\n" ); document.write( "ok \n" ); document.write( "

\n" );
