Math exercise 2.1

Solve the following questions. 1. Ans. = 7 + 2 [Adding 2 to both sides] = 9 2. Ans. = 10 – 3 [Subtracting 3 from both sides] = 7 3. Ans. [Subtracting 2 from both sides] 4. Ans. [Subtracting from both sides] 5. Ans. [Dividing both sides by 6] 6. Ans. = [Multiplying both sides by 5] = 50 7. Ans. [Multiplying both sides by 3] [Dividing both sides by 2] 8. Ans. [Multiplying both sides by 1.5] 9. Ans. [Adding 9 to both sides] [Dividing both sides by 7] 10. Ans. [Adding 8 to both sides] [Dividing both sides by 14] 11. Ans. [Subtracting 17 from both sides] [Dividing both sides by 6] 12. Ans. [Subtracting 1 from both sides] [Multiplying both sides by 3]
