Solve 2x + b = c for x

2x + b-b= c- b subtract b from both sides
2x=c-b combine like terms/simplify
2x - 2= c - b - 2 subtract 2 from both sides to get x isolated
x=c -b=2 simplify/final answer

Which statement is true?
O The process has an error. The correct answer is: x = (c - b) /2
O The process has an error. The correct answer is: x = c + b - 2
O The process is correct.
O The process has an error. The correct answer is: x = c/2 - b
