Question

2. x + 12 =23
3. X-6 = 13
4. X-9 = 14
5. 2x = 12
6. 3x = 30

Answer 1

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

Answer 2

2. x = 11

3. x = 19

4. x = 23

5. x = 6

6. x = 10

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
