If a unique solution does not exist, state whether the system is inconsistent or dependent. 5x – 2y = -5 and y – 5x = 3Answer by stanbon(57416)   (Show Source): You can put this solution on YOUR website!1st: 5x – 2y = -5 2nd: y – 5x = 3 3rd: 5x-2(5x+3)=-5 5x-10x-6=-5 -5x=1 x=-1/5 Substitute into 2nd to solve for "y", as follows: y-5(-1/5)=3 y=2 Check in 1st: 5(-1/5) - 2(2)=-5 -1-4=-5 Cheers, Stan H.
