document.write( "\r\n" );
document.write( "In accordance with the context of the problem, all the shirts have the same price.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Let x be the price for one shirt.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then Mr. Lee has, from one part of the condition,  3x + 6 dollars;\r\n" );
document.write( "\r\n" );
document.write( "                  from the other part of the condition, he has  5x - 10 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives you THIS EQUATION\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    3x + 6 = 5x - 10.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and find x\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    6 + 10 = 5x - 3x\r\n" );
document.write( "\r\n" );
document.write( "    16     = 2x\r\n" );
document.write( "\r\n" );
document.write( "     x     = 16/2 = 8 dollars.\r\n" );

document.write( "\r\n" );
document.write( "One shirt costs 8 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, Mr Lee has  3x + 6 = 3*8 + 6 = 30 dollars.    ANSWER\r\n" );
