The first step in solving the equation \( 2.4n - 6.4 = -14.8 \) is to isolate the term containing \( n \). You can do this by adding \( 6.4 \) to both sides of the equation to eliminate the constant on the left side.
So, the equation becomes:
\[ 2.4n - 6.4 + 6.4 = -14.8 + 6.4 \]
This simplifies to:
\[ 2.4n = -8.4 \]
Now you can proceed to solve for \( n \).
