Answer 1

The step that was taken to solve the equation \(3z^2 - 5 = 10\) by adding 5 to both sides of the equation is justified by the Addition Property of Equality.

This property states that if you add the same value to both sides of an equation, the two sides remain equal. In this case, adding 5 to both sides yields \(3z^2 - 5 + 5 = 10 + 5\).
