    The answer you are looking for is x = - 5.

    Step-by-step explanation:

    First, start by distributing the 3 and 2. This will remove the parentheses. The way you do this is by multiplying each number or variable inside the parentheses by the number outside the parentheses.

    3x + 3 = 2x - 2

    Next, get the variable to one side. One way to accomplish this is by subtracting 2x from each side.

    x + 3 = - 2

    Lastly, move the numbers to one side. Do this by subtracting 3 from both sides.

    x = - 5

    There you go. Your answer is now in the simplest form. Confirm the answer is as simple as plugging in - 5 for x in the original equation.
