#### 3.7.17 Matrix Tutorial Exercise 2

            x + a y = 6
            x + b y = 10

Just enter the righthand side vector, then divide by the lefthand side matrix as usual.

         1:  [6, 10]    2:  [6, 10]         1:  [6 - 4 a / (b - a), 4 / (b - a) ]
             .          1:  [ [ 1, a ]          .
                              [ 1, b ] ]
                            .

         ' [6 10] <RET>     ' [1 a; 1 b] <RET>      /

This can be made more readable using `d B` to enable Big display mode:

                   4 a     4
         1:  [6 - -----, -----]
                  b - a  b - a

Type `d N` to return to Normal display mode afterwards.
