    1) take the first part of the equation and work it by multiplying (x+2) by 3

    3 (x+2) + x

    3x + 6+x

    2) put the answer you got into the question you were given

    3x + 6+x = 2x + 16

    3) group the x variables and the non x variables

    3x + x - 2x = 16 - 6

    4) Now work the equation you have

    3x+x-2x=16-6

    4x-2x=16-6

    2x=16-6

    2x=10

    5) you divide both sides by the x variable

    2x=10

    2x/2 = 10/2

    x=5

    therefore x is 5
