Algebra.Com's Answer #69672 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! I have worked your problem two different ways and find that the answer that you give (x = 7) is just not possible. \n" ); document.write( "In the first place, to remove any ambiguity on the problem statement, please use parentheses! Why? Because... \n" ); document.write( "3/7x can be interpreted to mean either: \n" ); document.write( "Whereas, (3/7)x can be interpreted only as \n" ); document.write( "\n" ); document.write( "In the second place, the only way that I can get the answer that you give, (x = 7) is if the problem starts with \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Please check the original problem for a possible missing negative sign! \n" ); document.write( " \n" ); document.write( " |
