Let Numbers are x, y, z\r
\n" ); document.write( "\n" ); document.write( "x+y+z=45..............(1)
\n" ); document.write( "x=y+5
\n" ); document.write( "x-5=y
\n" ); document.write( "y=x-5.................(2)
\n" ); document.write( "x=2z
\n" ); document.write( "x/2=z
\n" ); document.write( "z=x/2..................(3)
\n" ); document.write( "Put the value of x from (2) and (3) to (1)\r
\n" ); document.write( "\n" ); document.write( "x+x-5+x/2=45
\n" ); document.write( "2x+x/2=45+5
\n" ); document.write( "2x+x/2=50
\n" ); document.write( "Multiply by 2 both sides
\n" ); document.write( "2*(2x+x/2)=50*2
\n" ); document.write( "4x+x=100
\n" ); document.write( "5x=100
\n" ); document.write( "5x/5=100/5
\n" ); document.write( "x=20
\n" ); document.write( "Put the value of x in (2) and (3)
\n" ); document.write( "y=x-5.................(2)
\n" ); document.write( "y=20-5
\n" ); document.write( "y=15
\n" ); document.write( "z=x/2..................(3)
\n" ); document.write( "z=20/2
\n" ); document.write( "z=10\r
\n" ); document.write( "\n" ); document.write( "So Numbers are 20, 15, 10
\n" ); document.write( " \n" ); document.write( "
\n" );
