AClear every parenthesis first
BCombine the like terms again
CDivide by the leading coefficient
DCheck the answer in the original
Answer & Solution
Correct answer: D. Check the answer in the original
1. Once the variable stands alone you have a candidate answer.
2. Put that value back into the equation you were first given.
3. If both sides come out equal, the answer is confirmed.
