Question

multiple-choice question
which algebraic expression has like terms?
2 + 3x

a + b

6z - 3z

5y + 4x

rewatch

Explanation:

Step1: Recall like terms definition

Like terms have same variable (or no variable) and same exponent.

Step2: Analyze each option

• \(2 + 3x\): 2 (constant) and \(3x\) (variable term) – not like terms.
• \(a + b\): Variables \(a\) and \(b\) are different – not like terms.
• \(6z - 3z\): Both terms have variable \(z\) with exponent 1 – like terms.
• \(5y + 4x\): Variables \(y\) and \(x\) are different – not like terms.

Answer:

The algebraic expression with like terms is \(6z - 3z\), so the correct option is the one with \(6z - 3z\) (the third option in the list: \(6z - 3z\)).
