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.

bash
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.
