To solve the equation 2x + 1 = 3 for x, you can apply the property of equality that allows you to perform the same operation on both sides of the equation. In this case, you can use the property of subtraction to subtract 1 from both sides of the equation, which gives:

2x + 1 - 1 = 3 - 1
2x = 2

Then, you can use the property of division to divide both sides of the equation by 2, which gives:

2x / 2 = 2 / 2
x = 1

Therefore, the solution to the equation is x = 1. The property of equality that you applied in this case was A) Subtraction and division.
