Answer 2

It looks like you've provided an equation for which you need a detailed explanation. Let's break it down step by step.

Solving the Equation |x| = 9

The equation |x| = 9 represents two separate equations: x = 9 and x = -9. This is because the absolute value of a number can be positive or negative. Therefore, the solutions for |x| = 9 are x = 9 and x = -9.

Solving the Equation 2|x| = 3

Similarly, the equation 2|x| = 3 can be split into two equations: 2x = 3 and 2x = -3. Solving for x in each equation gives us x = 3/2 and x = -3/2.

Solving the Equation 4 - x = 4 - (-x) + 16

To solve the equation 4 - x = 4 - (-x) + 16, we can start by simplifying the equation: 4 - x = 4 + x + 16 Next, we can combine like terms: 4 - x = 20 + x Now, let's isolate the variable x by moving all terms involving x to one side of the equation: 4 - x - x = 20 4 - 2x = 20 Subtract 4 from both sides: -2x = 16 Finally, divide by -2 to solve for x: x = -8

So, the solution to the equation 4 - x = 4 - (-x) + 16 is x = -8.

I hope this helps! If you have any more questions or need further clarification, feel free to ask.
