Let the ONE no. be y, the first no. be x and the third no. z
\n" ); document.write( "From the statement
\n" ); document.write( "y = 3 * x ----eqn1
\n" ); document.write( "z = x + 100 -----eqn 2
\n" ); document.write( "x + y + z = 405 -----eqn3\r
\n" ); document.write( "\n" ); document.write( "let's rearrange the eqns and sole the 3 simultaneous eqns.
\n" ); document.write( "3*x - y = 0
\n" ); document.write( "x - z = -100
\n" ); document.write( "x+y+z = 405\r
\n" ); document.write( "\n" ); document.write( "all the best
