Physics (vectors)

Could you please help me with this exercise? Thanks.
Adding and substracting vectors
Solve for the unknown variables:
(a) (a, b) + (3, 0) = (6, 7)
(b) (11, c) + (d, 5) = (-12, −3)
(c) (5, 5) + (e, 4) = (2, f)
(d) (-1, −3) − (5, g) = (h, 2)

    I'll do one of them, they are all the same and very easy

    b) (11,c) + (d,5) = (-12,-3)
    (11+d , c+5 ) = (-12,-3
    so 11+d = -12
    d = -23
    and c+5 = -3
    c = -8
