    -50=-2 (a+3)

    -2 (a+3) = -50

    -2 (a+3) / -2=-50/-2

    a+3=25

    a+3-3=25-3

    a=22

    a=22

    because

    -50=-2 (a+3) ... first distribute

    -50=-2a-6 ... then you want to get - 50 and - 6 on the same side

    so, add 6 to both sides and

    -44=-2a ... divide both sides by - 2

    a=22

    your welcome!
