2x + 3 = 9. What you need to do first, is to isolate the 'x' by itself. Subtract the 3 to the other side. 2x + 3 = 9. (Before subtraction) 2x = 6 (After subtraction) Then you can divide by whatever is on the 'x'. In this case, it is 2. (Before) 2x = 6 (After) x = 3. Now you can check the problem, so put in 3 for x. 2x + 3 = 9. 2(3) + 3 = 9. 6 + 3 = 9. 9 = 9.
