Answer:

  2(x -2) = 50

Step-by-step explanation:

The number that is 2 less than x is (x-2). Double that value is 2(x-2). When you say that doubled value will give 50, you mean it is equal to 50:

  2(x -2) = 50

__

The solution is found by dividing by 2, then adding 2.

  x -2 = 25 . . . . equation divided by 2*

  x = 27 . . . . . . 2 added to both sides of the equation*

_____

* Whatever you do to one side of the equation must also be done to the other side. That is how the sides remain equal.
