    Answer:

    Step-by-step explanation:

    2*x + 3 = 1/2x + 30             Subtract 3 from both sides

          – 3                -3

    2x = 1/2x + 27                     Subtract 1/2 x from both sides

    1/2 x  -1/2 x

    1 1/2 x = 27                         change 1 1/2 to 3/2

    3/2 x = 27                           Multiply by 2/3

    2/3 * 3/2x = 27 * 2/3

    x = 18
