Consider T(x,y) = (2x-y, -4x+2y), is T invertible? Why or why not? If so, compute the inverse, T-1, and compute the image of 8

Question

Consider T(x,y) = (2x-y, -4x+2y), is T invertible? Why or why not? If so, compute the inverse, T-1, and compute the image of 8 under the inverse map. ie. Compute T^-1
