Algebra.Com's Answer #774283 by Theo(13342) You can put this solution on YOUR website! a = alice's share \n" ); document.write( "b = bob's share \n" ); document.write( "m = mary's share\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "a + b + m = 25000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "their agreement was: \n" ); document.write( "a = 2 * m - 1000 \n" ); document.write( "b = m + 2000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "replace a and b with their equivalents to get: \n" ); document.write( "a + b + m = 25000 becomes: \n" ); document.write( "2 * m - 1000 + m + 2000 + m = 25000 \n" ); document.write( "combine like terms to get: \n" ); document.write( "4 * m + 1000 = 25000 \n" ); document.write( "subtract 1000 from both sides of the equation to get: \n" ); document.write( "4 * m = 24000 \n" ); document.write( "solve for m to get: \n" ); document.write( "m = 24000 / 4 = 6000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "a = 2 * m - 1000 becomes a = 2 * 6000 - 1000 which becomes a = 11000 \n" ); document.write( "b = m + 2000 becomes b = 6000 + 2000 which becomes b = 8000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you have: \n" ); document.write( "a = 11000 \n" ); document.write( "b = 8000 \n" ); document.write( "m = 6000 \n" ); document.write( "a + b + m = 11000 + 8000 + 6000 = 25000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "your solution is that: \n" ); document.write( "alice earned 11000 \n" ); document.write( "bob earned 8000 \n" ); document.write( "mary earned 6000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
