A student attempts to solve for x in the equation below. Which statement best applies to the work shown below?

3 = 2 _ x
3 = 2 _ 2 _ x
3 = _x
(-1)*3=(-1)-x
_3 = x
A.
The student incorrectly applied the multiplication property of equality before the addition property of equality.
B.
The student did not properly apply the addition property of equality to isolate x.
C.
The student did not properly apply the multiplication property of equality to isolate x.
D.
The student correctly solved the two-step equation.

Answer 1

As in step 2 the student added -2 only at one side of equation which is against the law of addition property of equality
so the correct option from above equation is
The student did not properly apply the addition property of equality to isolate x.
SO its B
