MEGA General Education 3 — Questions and Answers
Question 1: A student solves: 3x − 7 = 14 and gets x = 7. Which step verifies the solution?
- Substitute 7 for x: 3(7) − 7 = 21 − 7 = 14 ✓ (Correct answer)
- Divide both sides by 3 first to get x = 7/3
- Add 7 to 14 to get 21, then divide by 7
- Multiply both sides by x to eliminate the variable
Correct answer: Substitute 7 for x: 3(7) − 7 = 21 − 7 = 14 ✓
Substituting x = 7 back into the original equation confirms the solution when both sides are equal.
Question 2: Which literary device is used when an author gives human qualities to a non-human subject, as in 'The wind whispered through the trees'?
