13−2n=−109

Answer 1

To solve the equation \( 13 - 2n = -109 \), follow these steps:

1. Subtract \( 13 \) from both sides:

\[ -2n = -109 - 13 \]

This simplifies to:

\[ -2n = -122 \]

2. Next, divide both sides by \( -2 \):

\[ n = \frac{-122}{-2} \]

This simplifies to:

\[ n = 61 \]

So, the solution is:

\[ n = 61 \]
