 Question 580629: im brandon, the question i have is for algebra A. Its solving systems using substitution, problem is Y=x-4 and 2x-5y=2 . can you explain how to do this . Answer by mananth(13127)   (Show Source): You can put this solution on YOUR website! y = x-4 2 x + -5 y = 2 Substitute y in the second equation 2 x + -5 (x-4) = 2 2 x -5x+20 = 2 2 x -5 x = -18 -3 x = -18 / -3 x= 6 Plug the value of x in (1) -1 x + 1 y = -4 -1 * 6 + 1 y = -4 -6 + 1 y = -4 y=6-4 y = 2 m.ananth@hotmail.ca
