Question

Answer please.............

Answer 1

Option D: 1 is the correct answer.

Explanation:

Given that:

n(x) = 7x+4

n(x) = 11

Putting n(x) = 11 in first function.

11 = 7x + 4

Now, we will subtract 4 from both sides

11 - 4 = 7x + 4 - 4

7 = 7x

7x = 7

Dividing both sides by 7

`(7x)/(7)=(7)/(7)`

x = 1

Hence,

Option D: 1 is the correct answer.
