    Answer C. x = 2

    Step-by-step explanation:

    Given:

    x - 2y = 2

    3 * (x) + y = 6

    You need to group the x-coordinates of the system of equations.

    Rewrite x - 2y = 2, in such a way that it starts with x = ...

    x = 2y + 2

    Substitute x = 2y + 2 in 3 * (x) + y = 6, which gives:

    3 * (2y + 2) + y = 6

    6y + 6 + y = 6

    7y = 0

    y = 0

    Substitute y = 0 in x = 2 (y) + 2 gives x = 2*0 + 2

    So x = 2, which is answer C.

    x - 6x + 2x - 2x

    x - 6x + 0
