Answer: 4p – 3 = 13. Or, 4p = 13 + 3 = 16. Or, p = 16 ÷ 4 = 4. Hence, the value in the bracket is not correct. Question 3: Solve the following equations by trial and error method: 5p + 2 = 17. Answer: Let us assume, p = 1. Then, 5p + 2 = 5 X 1 + 2. Solution to the equation will give us the number which Sara held in her mind. Let us similarly look at. Solve the following equations by trial and error method: 5p + 2 = 17; 3m – 14 = 4. Write equations for the following statements: The sum of.
