1) To get equation B from equation A, we will add a quantity to the left hand side of equation A. The correct option is A. Add/subtract a quantity to/from only one side

2) The equations are not equivalent. They do not have the same solution

<h3>Equations</h3>

From the question, we are to determine how we can get equation B from equation A

From the given information,

A. 5x - 2 + x = x - 4

B. 5x + x = x - 4

From above, we can observe that to get equation B from equation A, we will add 2 to the left hand side of equation A

That is

5x - 2 + 2 + x = x + 4 → 5x + x = x + 4

Hence, to get equation B from equation A, we will add a quantity to the left hand side of equation A. The correct option is A. Add/subtract a quantity to/from only one side

2) The equations are not equivalent. They do not have the same solution
