document.write( "Left sides (x) in both equations must be equal; so equate right sides\r\n" );
document.write( "\r\n" );
document.write( "    23p - 4100 = -3p + 1100.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this equation, find p\r\n" );
document.write( "\r\n" );
document.write( "    23p + 3p = 4100 + 1100\r\n" );
document.write( "\r\n" );
document.write( "       26p   =    5200\r\n" );
document.write( "\r\n" );
document.write( "         p   =    5200/26 = 200.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then x = -3*200 + 1100 = -600 + 1100 = 500.\r\n" );
