I am glad that you asked this question and that is an easily solved mathematical problem since this is just a simple algebraic equation. The unknown variable here is obviously x and you are looking for the value of x when x +2 =11. Simple addition and subtraction is all you need in this equation.

To get the value of x, you subtract 2 from each side. It will give you

x+2=11

x+2-2=11-2

x=9

The value of x is 9.

To double check you could try plugging in the value of x you got back into the equation and see if the math works. This double checking by plugging method works not only in this case but in most of algebraic question.

x + 2 =11

This is addition, and what is the opposite operation of addition? (Subtraction). Subtract both sides by 2 to isolate x.

x=11-2

**x=9**

X + 2 = 11 :

To solve this equation , we have to get " x " alone. In order to get " x " alone subtract 2 on both sides

By subtracting 2 on both sides , you should get

X = 9 which is your answer

subtract 2 on both sides of the equation.

so it'd be x+2-2 = 11-2

11-2 is 9. 9 is your answer
