  • 2. 

    In the equation 3x - 3 = 9 , transporting -3 to RHS ,we get 3x = 9

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given equation is 3x - 3 = 9. To isolate the variable x, we need to move the constant term -3 to the right-hand side of the equation. By doing so, we should have 3x = 12. Therefore, the correct answer is False.

    Two different equations can never have the same answer

    • True

    • False

    Correct Answer
    A. False
    Explanation
    This statement is false because two different equations can indeed have the same answer. For example, the equations 2 + 2 = 4 and 3 + 1 = 4 both have the same answer of 4. Therefore, it is possible for different equations to yield the same result.

    Rate this question:

  • 4. 

    In the equation 2x = 4 - x , transporting - x to LHS, we get 3x = 4

    • True

    • False

    Correct Answer
    A. True
    Explanation
    By moving -x to the left-hand side of the equation, it becomes 3x = 4. This is a valid step in solving the equation. Therefore, the statement "3x = 4" is true.

    Rate this question:

  • 5. 

    3 years ago, the age of a boy was "y" years. His age 2 years ago was (y - 2 ) years

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement given in the question is incorrect. It states that the boy's age 2 years ago was (y - 2) years, but this is not necessarily true. The boy's age 2 years ago would be (y - 2) only if his age remained the same for the past 3 years. However, the question does not provide any information about the boy's age in the present or in the past, so we cannot assume that his age has remained constant. Therefore, the correct answer is False.
