First, we should simplify this to see if it is true. The left side is already in simplest form, but the right side isn't. It can be distributed, which is multiplying the numbers inside the parenthesis by two like this: [tex]2(x + 2) --> (2*x + 2*2) --> 2x + 4[/tex]. This equation has many solutions, because both sides both go through the same changes. So you are correct. Nice job. :)
