Answer 2

To evaluate the expression 8|6-х|-|у+4| when х = 7 and у = -9, we substitute these values into the expression and perform the calculations step by step:

Step 1: Replace х with 7 and у with -9 in the expression. 8|6 - х| - |у + 4|

Step 2: Calculate the value inside the absolute value bars for each case. |6 - 7| = |-1| = 1 |(-9) + 4| = |-5| = 5

Step 3: Substitute the calculated values back into the expression. 8 * 1 - 5

Step 4: Perform the multiplication and subtraction. 8 - 5 = 3

So, the value of the expression 8|6-х|-|у+4| when х = 7 and у = -9 is 3.
