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
