I would set them equal to each other
\n" ); document.write( "-1/2x+3=2x+8
\n" ); document.write( "add 1/2x to both sides
\n" ); document.write( "3=2.5x+8
\n" ); document.write( "subtract 8 from both sides
\n" ); document.write( "-5=2.5x
\n" ); document.write( "divide by 2.5
\n" ); document.write( "-2=x
\n" ); document.write( "y=-1/2x+3 and y=2x+8
\n" ); document.write( "y=2x+8
\n" ); document.write( "y=2*(-2)+8
\n" ); document.write( "y=-4+8=4
\n" ); document.write( "
\n" ); document.write( "
\n" );
