Answer 3

To solve the equation 7.2 - (2.9 + x) = -1.9, you can follow these steps:

1. Start by simplifying the equation within the parentheses:

   7.2 - (2.9 + x) = -1.9

   7.2 - 2.9 - x = -1.9

2. Now, subtract 2.9 from 7.2:

   4.3 - x = -1.9

3. To isolate the variable x, you can add x to both sides of the equation:

   4.3 - x + x = -1.9 + x

   4.3 = -1.9 + x

4. Finally, subtract -1.9 from both sides to solve for x:

   4.3 - (-1.9) = x

   4.3 + 1.9 = x

   6.2 = x

So, the solution to the equation is x = 6.2.
