    2. 23 - 12 = 11

    x = 11

    3. 13 + 6 = 19

    x = 19

    4. 14 + 9 = 23

    x = 23

    5. 12/2 = 6

    x = 6

    6. 30/3 = 10

    x = 10

    2. x = 11

    3. x = 19

    4. x = 23

    5. x = 6

    6. x = 10

    Step-by-step explanation:

    2. x + 12 = 23

    x = 23 - 12

    x = 11

    3. x - 6 = 13

    x = 13 + 6

    x = 19

    4. x - 9 = 14

    x = 14 + 9

    x = 23

    5. 2x = 12

    x = 12/2

    x = 6

    6. 3x = 30

    x = 30/3

    x = 10
