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.
