Q. When solving an equation, Bianca's first step is shown below. Which property justifies Bianca's first step?Original Equation:−4x=8First Step:x=−2addition property of equalitydistributive property of multiplication over additioncommutative property of additiondivision property of equality
Find x value: Bianca's original equation is −4x=8. Her first step is to find the value of x, which she states as x=−2. To go from −4x=8 to x=−2, Bianca must have divided both sides of the equation by −4. This is because dividing the term −4x by −4 isolates x, and dividing 8 by −4 gives x1. Calculation: x2 and x3
Division Property of Equality: By dividing both sides of the equation by −4, Bianca is using 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.No further calculations needed.
