Multiple Choice

Combine like terms: 2x + 3x + 5.

Explanation:
Combining like terms means adding the coefficients of terms that have the same variable. Here, 2x and 3x are like terms because both have x. Add their coefficients: 2 + 3 = 5, giving 5x. The constant 5 doesn’t have an x, so it stays separate as +5. Put together, the expression becomes 5x + 5. This shows how to group variable terms together and keep constants separate.
