Answer 3

To solve the equation, let's simplify the left side step by step:

20 - (12 - x) - (10 - x) - x = x - 2

First, let's deal with the parentheses:

20 - 12 + x - 10 + x - x = x - 2

Simplify the terms:

-2 + x - x = x - 2

The x terms on the left side cancel out:

-2 = x - 2

Now, add 2 to both sides to isolate x:

-2 + 2 = x - 2 + 2 0 = x

So, the solution to the equation is x = 0.
