Let the number be x and y \n" ); document.write( "as per 1st condition; \n" ); document.write( "x+y=135 ....(1)\r \n" ); document.write( "\n" ); document.write( "and as per second condition; \n" ); document.write( "2x = 280-3y \n" ); document.write( "or x = (280-3y)/2 ........(2)\r \n" ); document.write( "\n" ); document.write( "put the values of x from (2) into (1) and we get\r \n" ); document.write( "\n" ); document.write( "[(280-3y)/2] + y = 135\r \n" ); document.write( "\n" ); document.write( "solve the above equation and you get \n" ); document.write( "y= 10\r \n" ); document.write( "\n" ); document.write( "put the value of y in 1 and we get \n" ); document.write( "x = 125\r \n" ); document.write( "\n" ); document.write( "hope this will help you\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
