First lets expand it
Next lets simplify 27 - 12 + 2b and make it into 2b + 15
Next subtract 15 from both sides
Next subtract 96 - b - 15 and make it into 81 - b
Next add b to both sides
Next add b + 2b and make it into 3b
Then divide both sides by 3
And lastly reduce the fraction 81/3 to get the answer.
Answer: b = 27
