given the simultaneous equation below find x and y

1.  x-11=-54  | + 11

     x      = -54 + 11

     x      = -43

 

2.  6x-7y=41

     6*(-43) - 7y = 41

           -258 -7y = 41 | +258

                    -7y = 41 + 258

                    -7y = 299 | : -7

                        y = - 42 5/7
