Algebra.Com's Answer #304216 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! x+y=45 \n" ); document.write( "11x+10y= ?\r \n" ); document.write( "\n" ); document.write( "i've already tried 100, 80, & 81. all of them were no solution.\r \n" ); document.write( "\n" ); document.write( "i already know how to graph it & solving it algebraically . \r \n" ); document.write( "\n" ); document.write( "i just need help finding a number to make it a solution. \n" ); document.write( "-------------------------- \n" ); document.write( "Actually, you can put any number in place of the ?
