x+y=500...........(1)
\n" ); document.write( "5x+10y=3000.......(2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Take (2)
\n" ); document.write( "5(x+2y)=5(600)
\n" ); document.write( "Divide by 5 both sides
\n" ); document.write( "5(x+2y)/5=5(600)/5
\n" ); document.write( "x+2y=600...............(3)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract (1) from (3)
\n" ); document.write( "x+2y=600...............(3)
\n" ); document.write( "-x-y=-500..............(1)
\n" ); document.write( "--------------------------
\n" ); document.write( "y=100\r
\n" ); document.write( "\n" ); document.write( "Put the value of y in (1)
\n" ); document.write( "x+y=500...........(1)
\n" ); document.write( "x+100=500
\n" ); document.write( "x=500-100
\n" ); document.write( "x=400\r
\n" ); document.write( "\n" ); document.write( "x,y=400,100\r
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "=====
\n" ); document.write( "Put the value of x and y (1)
\n" ); document.write( "x+y=500...........(1)
\n" ); document.write( "400+100=500
\n" ); document.write( "500=500
\n" ); document.write( "Put the value of y in (2)
\n" ); document.write( "5x+10y=3000.......(2)
\n" ); document.write( "5(400)+10(100)=3000
\n" ); document.write( "2000+1000=3000
\n" ); document.write( "3000=3000 \n" ); document.write( "
\n" );
