Given the system of equations 2x + 3y = 1 and 14x + 21y = 7, which one of the following statements is true? \n" ); document.write( "The system has no solutions. \n" ); document.write( "The system has one and only one solution (-1,1). \n" ); document.write( "The system has infinitely many solutions. \n" ); document.write( "The system has one and only one solution (7,7) \n" ); document.write( "------------------ \n" ); document.write( "The 2nd eqn is 7 times the 1st, so they're dependent. \n" ); document.write( "1 eqn in 2 unknowns is a line, with an infinite number of solutions. \n" ); document.write( "----------- \n" ); document.write( "BTW, (7,7) is not a solution. \n" ); document.write( " |
