y=-3x+19
\n" ); document.write( "y=2x-1
\n" ); document.write( "2x-1=-3x+19
\n" ); document.write( "5x=20
\n" ); document.write( "x=4
\n" ); document.write( "---------------
\n" ); document.write( "y=2(4)-1
\n" ); document.write( "y=7
\n" ); document.write( "---------------
\n" ); document.write( "7=-3(4)+19
\n" ); document.write( "7=-12+19 \n" ); document.write( "
