This implies that |x-(12-5x)| = 6. \n" ); document.write( "|x-12+5x| = 6. \n" ); document.write( "|6x-12| = 6, \n" ); document.write( "|x-2| = 1, after dividing both sides by 6. \n" ); document.write( "Then x-2 = 1 or x-2 = -1. The first equation gives x = 3, and the second, x = 1. If x = 3, y = -3. If x = 1, y = 7. The answers are then (3,-3) or (1,7). \n" ); document.write( " |
