Answer 2

Answer:

The person who completed the proof incorrectly is:

                 Option: B

                   B)  Sasha

Answer with explanation:

Sasha was incorrect with her proof.

She followed as follows:

• 3x+7=5x-11      Given

• 7=2x-11

( She subtracted 3x from both the sides of the equation)

Hence, the property is subtraction property of equality.

• 18=2x

She added 11 on both the sides of the equation.

Hence, the property is addition property of equality.

• x=9

she divided both side of the equation by 2.

Hence, the property is division property of equality but she called it as a subtraction property of equality.
