    Answer:

    a = 10

    Step-by-step explanation:

    And to Solve this equation we write it like this

    A= 9 multiplied by 2 + 2x + A

    2a = 18 + 2x

    So, Lets keep the “x” aside and see

    2a = 18 + 2

        = 20

    a = 20 upon 2 or (20/2) = 10

    a= 10

    So now there’s a question whats “x”

       = 18 + 2x + 10

       = 28 + 2x

    x = 28 +2

    x = 30

    Now, solving the equation:

    9 multiplied by 2 added to 2 and then multiplied with 30 and again added to 10

      = 18 + 2 * 30 + 10

      = 60 + 10 + 18

      = 70 + 18

      = 88

    Voila!! you’ve got it
