Algebra.Com's Answer #347069 by umail08(87)![]() ![]() You can put this solution on YOUR website! Let x = larger number \n" ); document.write( "Let y = smaller number \n" ); document.write( "x – y = 10 … since the difference is positive then you must subtract the smaller from the larger \n" ); document.write( "x = 2y – 7 … larger number is twice the smaller decreased by 7 \n" ); document.write( "Solve system of equations: \n" ); document.write( "1) x – y = 10 \n" ); document.write( "2) x = 2y – 7\r \n" ); document.write( "\n" ); document.write( "1) x – y = 10 \n" ); document.write( "2) x – 2y = -7\r \n" ); document.write( "\n" ); document.write( "Subtract #2 from #1 \n" ); document.write( "y = 17 \n" ); document.write( "1) x – y = 10 \n" ); document.write( "x – 17 = 10 \n" ); document.write( "x = 27 \n" ); document.write( " \n" ); document.write( " |
