Пошаговое объяснение:

Answer 2

To evaluate the expression 4x - 8x - 5 + 6 when x = 3, we substitute x with 3 and perform the calculations.

Replacing x with 3, we get:

4(3) - 8(3) - 5 + 6

Simplifying the expression:

12 - 24 - 5 + 6

Next, we combine like terms:

-12 - 5 + 6

Now we perform the addition and subtraction:

-17 + 6

Finally, adding -17 and 6:

-11

Therefore, when x = 3, the expression 4x - 8x - 5 + 6 equals -11.
