  1. From line 2, he should be doing this instead
    27 = 18(1+5r)
    27 = 18+90r
    -90r = -5
    r = 1/18

  2. The error occurs at line 2. There should not be a multiplication sign from line 2 onwards.

    Line 2 should have been:

    27= 18(1+5r)
    27= 18+90r

    Line 1's brackets are also wrong. The main bracket enclosing the second, third and fourth terms should be [ ] and not ( ).
