Question

11 + 2/9b = 23
solve for b:

Answer 1

b= 54

Step-by-step explanation:

11 + 2/9b = 23

2/9b = 23 -11

2/9b = 12

2 x 9b/9b = 12 x 9b

2 = 12 x 9b

12 x 9b = 2

108b = 2

b = 2/108

b = 1/54

Answer 2

Answer: b = 2/ 81

Step-by-step explanation: From the question

11 + 2/ 9b = 23

Subtract 11 from both sides

11 - 11 + 2/ 9b = 23 -11

It becomes 2/ 9b = 12 (12 can also be written like this: 12/ 1)

Cross multiply

9b * 12 = 2 * 1

81b = 2

b = 2 / 81
