Also, are the equations equivalent?

Choice A) Add/subtract the same quantity from both sides

Specifically, we subtract 2x from both sides

On the left side, we'll have 2x-2x turn into 0x and that's just 0. So the x terms go away on the left side. On the right side, 5x-2x turns into 3x.

The equations A and B are equivalent because of this. The property used is the subtraction property of equality. It's very similar to the addition property of equality.
