Which option gives the correct simplified form of (6xy-2x+3xy+5x)?
Answer and explanation
Correct answer: \(9xy+3x\)
Combine like terms: \(6xy+3xy=9xy\) and \(-2x+5x=3x\). Therefore, the simplified expression is \(9xy+3x\). The terms \(xy\) and \(x\) are unlike terms, so they cannot be combined with each other. Exam tip: Add or subtract coefficients only when the variables and their powers are exactly the same.
