Explanation

Choice A is correct. Dividing each side of the given equation by 7 yields 72x-37=637, or 2x-3=9. Therefore, the equation 2x-3=9 is equivalent to the given equation and has the same solution.

Choice B is incorrect. This equation is equivalent to 72x-3=392, not 72x-3=63.

Choice C is incorrect. Distributing 7 on the left-hand side of the given equation yields 14x-21=63, not 2x-21=63.

Choice D is incorrect. Distributing 7 on the left-hand side of the given equation yields 14x-21=63, not 2x-21=70.
