When solving an equation, Gabrielle's first step is shown below. Which property justifies Gabrielle's first step? Original Equation: -x-4=-4 First Step: -x=0 distributive property of multiplication over addition associative property of multiplication addition property of equality commutative property of multiplication

Addition Property of Equality: Gabrielle's first step is to go from the original equation -x - 4 = -4 to -x = 0. To do this, she adds 4 to both sides of the equation. This step is justified by the addition property of equality, which states that if you add the same number to both sides of an equation, the equality is still maintained. Calculation: -x - 4 + 4 = -4 + 4 results in -x = 0.
