Answer:

5k - 2

Step-by-step explanation:

To evaluate f(2 - k), substitute x = 2 - k into f(x), that is

f(2 - k) = 8 - 5(2 - k) = 8 - 10 + 5k = 5k - 2

Answer:

Your answer is 3x = 15

Step-by-step explanation:

3x = 15

Since 3 is being multiplied by x, we divide both sides by 3. 3x/3 cancels out, and you're left with x.

15/3 = 5

x = 5

This is my take using algebraic methods.
