Answer 2

I can help you solve these equations. Let's start with the first one: |1-x| = -2.

The absolute value of a number is always non-negative, so there is no real solution for this equation. You can see this by graphing the function y = |1-x| and the line y = -2 on a coordinate plane. They will never intersect.

The second equation is |x-1| = 2. This means that the distance between x and 1 is 2 units on the number line. There are two possible values for x that satisfy this condition: x = -1 and x = 3. You can check this by plugging in these values into the equation and see that they make it true. You can also graph the function y = |x-1| and the line y = 2 on a coordinate plane and see that they intersect at these points.

The third equation is 3-x = 0. This is a simple linear equation that can be solved by adding x to both sides. You will get x = 3 as the only solution. You can graph the function y = 3-x and the line y = 0 on a coordinate plane and see that they intersect at this point.

I hope this helps you understand how to solve these equations. If you need more help, you can use the web search results I found for you.
