    D

    2x+1=3

    -1 on both sides: 2x=2, then divide by two. You get x=1

    x = 1

    D) Subtraction and Division

    Step-by-step explanation:

    2x + 1 = 3

    (2x + 1) - 1) = (3) - 1 ←

    2x = 2

    (2x) / 2 = (2) / 2 ←

    x = 1

    In the places where I put the arrows is where I applied the properties. I used subtraction and division to solve.
