Answer 1

11n-7n+1-6n+8
-2n+9
-2×(-6)+9=12+9=21

Answer 2

To evaluate the expression 11n - (7n - 1) - 6n + 8 when n = -6, follow these steps:

Step 1: Replace n with -6 in the expression: 11(-6) - (7(-6) - 1) - 6(-6) + 8

Step 2: Perform the operations inside parentheses first: 11(-6) - (-42 - 1) - 6(-6) + 8

Step 3: Simplify the expression inside the parentheses: -66 - (-43) - 6(-6) + 8

Step 4: Continue with the subtraction and multiplication: -66 + 43 + 36 + 8

Step 5: Perform the remaining additions: 43 + 36 + 8 = 87

So, the value of the expression 11n - (7n - 1) - 6n + 8 when n = -6 is 87.
