Algebra.Com's Answer #249842 by mananth(16946) You can put this solution on YOUR website! let one number be x \n" ); document.write( "the other number will be 1200-x. ( Because the sum of both is 1200) \n" ); document.write( ".. \n" ); document.write( "one number is 800 less than the 3 times the other. \n" ); document.write( "The other number is 1200-x \n" ); document.write( "3 times other = 3(1200-x) \n" ); document.write( "less 800 \n" ); document.write( "= 3(1200-x) -800 \n" ); document.write( "x=3(1200-x)-800 \n" ); document.write( "x=3600-3x-800 \n" ); document.write( "x+3x= 2400 \n" ); document.write( "4x = 2400 \n" ); document.write( "divide by 4 \n" ); document.write( "x= 2400/4 \n" ); document.write( "x=600 \n" ); document.write( "if one number is 600, then other is 1200-x=600. \n" ); document.write( " |
