  1. I think you forgot to say how many offer English. Using what you have given, all we know is that if
    E took English
    x took all three, then
    (22+36+E)-(8+10+12)+x = 60-6
    E+x = 26
    So there are lots of possible solutions.

  2. The question is incomplete. 22 also offered English.
    Therefore
    22 + x = 26
    x = 26 - 22
    x = 4

    History only = 14 + x = 14 + 4 = 18

    French and history only = 12 - x = 12 - 4 = 8
