X+2y=2x-5, X-y=3 - System Of Equations Calculator - Symbolab

при x = - 2 , y = - 5 .If x+y=5, then x=5-y(hope u can solve for x). This means that we can use 5-y in place of x in the second equation to find y. So (xy=6) now becomes (5-y)y = 6. Now expand the left side to get 5y-y^2=6. (y^2 means y squared). What you have here are two equations: [math]x+y=5[/math]...
