Algebra.Com's Answer #126635 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! 5.5x-1.5y=3.5x \n" ); document.write( ": \n" ); document.write( "2x-1.5y=0....yes x=3 and y =4 works but so does x=6 and y=8 and x=1 and y=4/3......The answers are actually infinite. In order to get a one solution answer there has to be something to compare it to. \n" ); document.write( " |
