My teacher gave me a question that I struggled with. I was requested to find x from a given equation: ABC^tx^-1BA^tC=AB^t Basically, he manipulated the equation in A^tB^-1A^-1 and I didn't understand the whole idea inside the solution, so I will be really glad if someone can help me with the confusion.
