#EASY WILL MARK BRAINLEST:D

I believe that the answer would be: 5.
This is how i did it:
Wherever it said (x), I substituted the value for x by putting in 5.
Then, I got 2(15-5/5-1)
After that, I simplified and got 2(10/4)
Then, I multiplied 2 x 10/4 and I got 10/2
Finally, I simplified 10/2 and got 5.
Answer:
The correct answer is 5
Step-by-step explanation:
1. Replace x with 5:
f(5) = 2(3(5)-5/5-1)
2. Simplify:
f(5) = 2(15-5/5-1)
f(5) = 2(10/4)
3. Simplify further:
f(5) = 2(5/2)
4. Multiply 2 and 5/2:
10/2 = 5
