Question

simplify the expression: 3x + 2x

Explanation:

Step1: Identify like terms

The terms \(3x\) and \(2x\) are like terms because they have the same variable part \(x\).

Step2: Combine like terms

To combine like terms, we add the coefficients. The coefficient of \(3x\) is 3 and the coefficient of \(2x\) is 2. So, \(3 + 2 = 5\). Then we attach the variable \(x\) to the sum of the coefficients. So, \(3x + 2x=(3 + 2)x = 5x\).

Answer:

A. \(5x\)
