Hi, Alexandra!
First, multiply 2 by the x in the parentheses. That gives you 2x. Then multiply that 2 by the 2 in the parentheses - that gives you 4. So... 2(x+2) = 2x + 4. Then, minus 4x. So you have -2x + 4 = 12. Subtract the four from both sides to eliminate it -2x = 8.
Can you find the answer now?
