Hint
Reveal a hint
Check the operator in the second equation and where a spare equals sign can come from.
Why It Works
The second equation reads incorrectly because the plus sign should be an equals sign to make its numbers balance. The third equation happens to have the equals sign you need, so you move it over. Replacing the operator turns the faulty equation into a true statement.
