Q: Simplify: \(3x + 2x - 4\).

Did You Know?

FALSE. While tense usually changes (backshift), there are exceptions. If the statement is still true or relevant at the time of reporting, we may not change the tense. Example: Direct: 'The Earth revolves around the sun,' she said. Indirect: She said that the Earth revolves around the sun. (Universal truth - no tense change). Also, if the reporting happens very soon after the original speech, tense may not change.
