document.write( "Let Kuz' age be x, the Lebron's age is (x+5)
\n" );
document.write( "The product of their ages is 21 years less than 15 times the sum of their ages

document.write( "Write as You Read:
\n" );
document.write( "x(x+5) = 15(x + (x+5)) -21
\n" );
document.write( "Simply and solve:
\n" );
document.write( "x^2 + 5x  = 15(2x+5)-21
\n" );
document.write( "x^2 + 5x = 30x + 75 - 21
\n" );
document.write( "x^2 -25x - 54 = 0
\n" );
document.write( " x = 27    (tossing out negative value)
\n" );
document.write( "Kuz is 27 years old
