5003 Praxis Practice Test Practice Question
Which of the following statements is true?
Correct Answer: B
Rationale: Option B is accurate because dividing both sides of an equation by the same nonzero number maintains the equality, a fundamental property of equations.
Option A is misleading; while adding a nonzero number to an expression changes its value, it does not result in an equivalent expression, as equivalence implies both expressions have the same value.
Option C is incorrect; multiplying or dividing an expression by a nonzero number changes its value, thus not yielding an equivalent expression.
Option D is also false; adding an algebraic expression to one side of an equation without doing the same to the other side disrupts the balance, leading to an inequivalence.
