can anyone help please!! yes and I am sorry i am re posting a question again. use a method of substitution to solve the system of linear equation these system may have no solution, or infinitely many solutions. x+y=-2 x+y=3
a) x + y = -2 b) x + y = 3 you could isolate x in equation (a) then sub in the result in equation (b) but in this case that is overkill the left hand side of both equations are equal so subbing (a) into (b) we get -2 = 3 This answer is nonsense and the system has no solution.
