Answer 2

To solve the equation 42.9 - (x + 12.97) = 13.91, you can follow these steps:

1. Start by simplifying the equation:

   42.9 - (x + 12.97) = 13.91

   First, distribute the negative sign inside the parentheses:

   42.9 - x - 12.97 = 13.91

2. Next, combine like terms on the left side of the equation:

   42.9 - 12.97 - x = 13.91

   Now, subtract 12.97 from 42.9:

   29.93 - x = 13.91

3. Isolate the variable x by moving the 29.93 to the other side of the equation. You can do this by subtracting 29.93 from both sides:

   -x = 13.91 - 29.93

   -x = -16.02

4. Finally, to solve for x, multiply both sides of the equation by -1 to get x by itself:

   x = 16.02

So, the solution to the equation is:

x = 16.02
