Identify Equation: Gabrielle's first step in solving the equation is going from −5x=−20 to x=4. To determine which property justifies this step, we need to look at the operations performed. Gabrielle divided both sides of the equation by −5 to isolate x. This is an application of the division property of equality, which states that if you divide both sides of an equation by the same nonzero number, the two sides remain equal.Calculation: −5x/−5=−20/−5 leads to x=4.
