Answer 2

To solve the equation, you need to perform the arithmetic operations in the correct order, following the rules of addition and subtraction. Let's break it down step by step:

31 + (-68.2) + 9

First, simplify the addition of 31 and 9:

31 + 9 = 40

Now, let's add the negative number (-68.2):

40 + (-68.2)

To add a negative number, you can think of it as subtracting the absolute value of the number. So, in this case, it becomes:

40 - 68.2

Performing the subtraction:

40 - 68.2 = -28.2

Therefore, the solution to the equation 31 + (-68.2) + 9 is -28.2.
