    Hello, I am having difficulty with answering this question, it'd be very much appreciated if some help could be giving to the solution and an explanation as to how it is done!☺️X
    What have you tried? Try pre-multiplying by b^(-1), etc... post-multiply by the appropriate element till you isolate x using the fact that
    elemeent * inverse = identity and anything * identity = anything.
