Algebra.Com's Answer #223774 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! Let x = total number of coins in the collection \n" ); document.write( ": \n" ); document.write( "w, y, z, the number of coins had by each person \n" ); document.write( ": \n" ); document.write( "A collection of coins is to be divided amongst 3 people so that \n" ); document.write( "\"the second person has 8 more than the first person\" \n" ); document.write( "y = w+8 \n" ); document.write( "Or \n" ); document.write( "w = y-8 \n" ); document.write( "; \n" ); document.write( "\" and the third person has 6 fewer coins than the second,\" \n" ); document.write( "z = y-6 \n" ); document.write( ": \n" ); document.write( "how many coins should each person get? \n" ); document.write( ": \n" ); document.write( "w + y + z = x \n" ); document.write( "replace w & z \n" ); document.write( "(y-8) + y + (y-6) = x \n" ); document.write( "3y - 14 = x \n" ); document.write( "3y = x + 14 \n" ); document.write( "y = \n" ); document.write( ": \n" ); document.write( "We know y > 8 and is an integer, using the above equation: \n" ); document.write( "when x = 13, y = 9 \n" ); document.write( "see if that works \n" ); document.write( "w = 9 - 8 \n" ); document.write( "w = 1 \n" ); document.write( "z = 9 - 6 \n" ); document.write( "z = 3 \n" ); document.write( ": \n" ); document.write( "Total 1 + 9 + 3 = 13 \n" ); document.write( ": \n" ); document.write( "However, there are many other solutions \n" ); document.write( "x=16, y=10 \n" ); document.write( "x=19, y=11 \n" ); document.write( "x=22, y=12 are just a few \n" ); document.write( " \n" ); document.write( " |
