Answer: X = 11

Step-by-step explanation: Since our variable, in this case x appears on both sides of the equation, we want to put our x terms together on one side of the equation and put our numbers together on the other side of the equation.

So let's put our x's together on the left side of the equation and we do that by subtracting 2x from both sides. On the left, we have X + 1 and on the right, the 2x and -2x cancel each other out and we are left with 12.

So we have X + 1 = 12.

Now we want to put our numbers together on the right side of the equation and we do that by subtracting 1 from both sides.

On the left, +1 and -1 cancel and we have x. On the right, 12 - 1 is 11.

Now we have x = 11 which is the solution to our equation.
