#### 2.7.17 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:  [4 a / (a - b) + 6, 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, -----]
         a - b      b - a

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