Algebra.Com's Answer #34301 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! One number is 6 less than another. Three times the smaller is 2 more than twice the larger. Find the numbers. \n" ); document.write( "Let the smaller number be y; the larger be x. \n" ); document.write( "EQUATION: \n" ); document.write( "1st: x-y=6 \n" ); document.write( "2nd: 3y-2=2x \n" ); document.write( "Solving by substitution solve 1st by x: \n" ); document.write( "3rd: x=y+6 \n" ); document.write( "Substitute into 2nd to get: \n" ); document.write( "3y-2=2(y+6) \n" ); document.write( "3y-2=2y+12 \n" ); document.write( "y=14 \n" ); document.write( "x=y+6=20 \n" ); document.write( "SOLUTION: x=20; y=14\r \n" ); document.write( "\n" ); document.write( "--------------------------------------------------\r \n" ); document.write( "\n" ); document.write( "Bill has twice as much money as Bob.
