First... \n" ); document.write( "One number (n) is 12 more than another (n+12). \n" ); document.write( "The sum of the smaller number (n) \n" ); document.write( "and twice the larger number + 2(n+12) \n" ); document.write( "is 39 (=39) \n" ); document.write( "So lets put that formula together. \n" ); document.write( "n + 2(n + 12) = 39 \n" ); document.write( "Distribute... \n" ); document.write( "n + 2n + 24 = 39 \n" ); document.write( "Subtract 24 from each side... \n" ); document.write( "n + 2n = 15 \n" ); document.write( "Add like terms... \n" ); document.write( "3n = 15 \n" ); document.write( "Divide both sides by 3... \n" ); document.write( "n = 5 \n" ); document.write( "So, the smaller number (n) = 5 \n" ); document.write( "The larger number (n + 12) = 17 \n" ); document.write( "The correct answer is... a. 17 \n" ); document.write( " \n" ); document.write( " |
