If the system has no solution or an infinite number of solutions, state this. 10x – y = 12.5 3x + y = 7 Answer by mananth(13126)   (Show Source): You can put this solution on YOUR website!10 x - y = 12.50 .............1 3 x + y = 7 .............2 Eliminate y Add the two equations 13 x = 20 / 13 x = 20/13 plug value of x in (1) 10 x - y = 13 200/13 - y = 13 - y = 13 -200/13 - y = -31/13 y = 31/13 It has a unique solution (20/13, 31/13)
