Q. When solving an equation, Francesca's first step is shown below. Which property justifies Francesca's first step?Original Equation:x+4=−2First Step:x=−6multiplication property of equalitydivision property of equalitycommutative property of additionsubtraction property of equality
Initial Equation: Francesca's first step in solving the equation is to go from x+4=−2 to x=−6. This step involves removing 4 from both sides of the equation. This is done to isolate the variable x on one side of the equation. The property that justifies this action is the subtraction property of equality, which states that if you subtract the same number from both sides of an equation, the two sides remain equal.Calculation: x+4−4=−2−4 results in x=−6.
