Algebra.Com's Answer #366651 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! \"Victor has 8 coins\" ___ p + n + d = 8\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "\"He has 2 fewer dimes than nickels\" ___ d = n - 2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "\"one more penny than nickels\" ___ p = n + 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "substituting ___ (n + 1) + n + (n - 2) = 8 ___ 3n - 1 = 8 ___ n = 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "use the value of n to find p and d \n" ); document.write( " |
