Algebra.Com's Answer #6911 by glabow(165)![]() ![]() ![]() You can put this solution on YOUR website! No, you have a simple error. If y is the number of tickets sold for couples, then 2y persons attend for those tickets. So, x + 2y = 128. Your equation for the dollar amount of x and y ticket sales is correct. \n" ); document.write( "Solve x + 2y = 128 and 20x + 35y = 2280. \n" ); document.write( "[I got x=16 and y=56] \n" ); document.write( " \n" ); document.write( " |
