    Answer: x = 2.5

    Step-by-step explanation: To solve this equation, we start by distributing the 3 through the parenthses on the left side.

    So we have 3 (2x) which is 6x and 3 (-3) which is - 9.

    So our equation now reads 6x - 9 = 6.

    Solving from here, we need to isolate the term containing x which is 6x.

    Since 9 is being subtracted from 6x, we add

    9 to both sides of the equation to isolate the 6x.

    On the left, the - 9 and + 9 cancel out and on the right, 6 + 9 is 15.

    So we have 6x = 15.

    Now we can finish things off by just

    dividing both sides of the equation by 6.

    On the left the 3's cancel and on the right, 15 divide by 6 is 2.5.

    So x = 2.5.

    Option A & D

    Step-by-step explanation:

    => 3 (2x-3) = 6

    => 6x-9 = 6

    => 6x = 6+9

    => 6x = 15

    Dividing both sides by 6

    => x = 2.5
