Question

1. 1 - 4n = 49

Explanation:

Step1: Subtract 1 from both sides

To isolate the term with \( n \), we subtract 1 from both sides of the equation \( 1 - 4n = 49 \). This gives us \( 1 - 4n - 1 = 49 - 1 \), which simplifies to \( -4n = 48 \).

Step2: Divide by -4

Now, to solve for \( n \), we divide both sides of the equation \( -4n = 48 \) by -4. So, \( \frac{-4n}{-4} = \frac{48}{-4} \), which simplifies to \( n = -12 \).

Answer:

\( n = -12 \)
