\r\n" );
document.write( "Let x be the number of the jeans sold of the brand A.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of those of the brand B is (32-x).\r\n" );

document.write( "\r\n" );
document.write( "Your \"money\" equation is \r\n" );
document.write( "\r\n" );
document.write( "30x + 35*(32-x) = 1050.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve for x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "30x + 1120 - 35x = 1050\r\n" );
document.write( "\r\n" );
document.write( "-5x = 1050 - 1120 = -70  ====>  x =  = 14.\r\n" );
