Q. Dustin solved this equation:6.6(2y−4)=y−213.2y−26.4=y−212.2y−26.4=−212.2y=24.4y=2Which property is not needed to justify any of the steps?Choices:(A) division property of equality(B) commutative property of multiplication(C) addition property of equality(D) distributive property
Expand Equation: Expand the equation using the distributive property.Calculation: 6.6(2y−4)=6.6×2y−6.6×4=13.2y−26.4
Simplify Equation: Simplify the equation by subtracting y from both sides.Calculation: 13.2y−26.4=y−2→13.2y−y=−2+26.4→12.2y=24.4
Solve for y: Solve for y by dividing both sides by 12.2.Calculation: 12.2y=24.4→y=12.224.4→y=2
