    the answer is a=8

    Explanation:

    3a-7=9+a

    Step 1: Simplify both sides of the equation.

    3a-7=9+a

    3a+-7=9+a

    3a-7=a+9

    Step 2: Subtract a from both sides.

    3a-7-a=a+9-a

    2a-7=9

    Step 3: Add 7 to both sides.

    2a-7+7=9+7

    2a=16

    Step 4: Divide both sides by 2.

    2a/2 = 16/2
