    C and E

    Step-by-step explanation:

    Substitute ( - 6, 2) into the left side of each equation and if equal to the right side then that is a possible equation

    A

    2 ( - 6) - 3 (2) = - 12 - 6 = - 18 ≠ - 6

    B

    4 ( - 6) - 2 = - 24 - 2 = - 26 ≠ 26

    C

    3 ( - 6) + 2 (2) = - 18 + 4 = - 14 ← this is correct

    D

    - 6 - 2 = - 8 ≠ - 2

    E

    - 6 + 2 = - 4 ← This is correct

    Thus the 2 possible equations are C and E
