Question

f(n) = 4 - 10n if f(n) = 14, what is the value of x?

Explanation:

Step1: Set up the equation

We know that \( f(n)=4 - 10n \) and \( f(n) = 14 \), so we set up the equation \( 4-10n=14 \).

Step2: Subtract 4 from both sides

Subtract 4 from each side of the equation: \( 4-10n - 4=14 - 4 \), which simplifies to \( - 10n=10 \).

Step3: Solve for n

Divide both sides by - 10: \( n=\frac{10}{-10}=-1 \). Wait, but the question mentions "what is the value of x?". There might be a typo, and it should be "what is the value of n?". Assuming that, the value of n is - 1.

Answer:

-1
