What is the simplified form of (x+2y+x+3y)?
Advertisement
Answer and explanation
Correct answer: \(2x+5y\)
Combine like terms: \(x+x=2x\) and \(2y+3y=5y\). Therefore, the simplified expression is \(2x+5y\). \(5xy\) is incorrect because adding terms containing \(x\) and \(y\) does not multiply them. Exam tip: Add only terms with the same variable and the same power.
