Answer 3

To solve the equation 2-x=9, you want to isolate x on one side of the equation. You can do this by performing the same operation on both sides of the equation until x is by itself.

Starting with 2-x=9:

1. Subtract 2 from both sides to eliminate the 2 on the left side:

   2 - 2 - x = 9 - 2

   -x = 7

2. Divide both sides by -1 to solve for x:

   -x/-1 = 7/-1

   x = -7

Therefore, the solution to the equation 2-x=9 is x=-7.
