Solve by the elimination method \n" ); document.write( "2x + 3 y = 2 \n" ); document.write( "4x + 6y = 4 \n" ); document.write( "---------------------- \n" ); document.write( "multiply thru the 1st equation by 2: \n" ); document.write( "4x + 6y = 4 \n" ); document.write( "---- \n" ); document.write( "Subtract that from the 2nd equation and you get: \n" ); document.write( "0 = 0 \n" ); document.write( "------------ \n" ); document.write( "That means the 2nd equation is simply a multiple \n" ); document.write( "of the 1st. The two equations give you the same \n" ); document.write( "set of points. \n" ); document.write( "Each point is of the form (x, (-2/3)x + (2/3)) \n" ); document.write( "----- \n" ); document.write( "The system is said to be dependent because one \n" ); document.write( "equation is a multiple of the other. \n" ); document.write( "===================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
