To solve the equation \( x - 3.41 = -19 \) for \( x \), you need to isolate \( x \) by getting rid of the \(-3.41\).
To do this, you should add 3.41 to both sides of the equation. This will give you:
\[ x - 3.41 + 3.41 = -19 + 3.41 \]
Which simplifies to:
\[ x = -19 + 3.41 \]
So the correct response is:
add 3.41.
