To solve the equation \( x - 3.41 = -19 \) for \( x \), you want to isolate \( x \) on one side of the equation.
You can do this by adding \( 3.41 \) to both sides of the equation.
So the correct operation to perform on both sides is:
add 3.41
This would look like:
\[ x - 3.41 + 3.41 = -19 + 3.41 \]
Which simplifies to:
\[ x = -15.59 \]
