To solve the expression |-23| + |+7| - |-9|, we evaluate the absolute values first, and then perform the addition and subtraction operations.

The absolute value of a number is its magnitude, ignoring the sign.

|-23| is equal to 23 since the absolute value of -23 is 23. |+7| is equal to 7 since the absolute value of +7 is 7. |-9| is equal to 9 since the absolute value of -9 is 9.

So, the expression becomes:

23 + 7 - 9

Now we can perform the addition and subtraction:

23 + 7 = 30 30 - 9 = 21

Therefore, the value of |-23| + |+7| - |-9| is 21.
