Answer: 3.13 :)

Step-by-step explanation:

8(1+8)-23b=b

Distribute

8+64-23b=b

72-23b=b

72=23b

3.13=b

8(1+8)-23b=b

mutiply the bracket by 8

(8)(1)= 8

(8)(+8)= 64

8+64-23b= b

72-23b=b

move -23b to the other side

sign changes from -23b to +23b

72-23b+23b= b+23b

72=b+23b

72= 24b

divide by 24 for both sides

72/24= 24b/24

Cross out 24 and 24, divide by 24 and then becomes 1*1*b= b

b= 3

Answer: b= 3
