Question: 1 / 400

How do you simplify the expression 2x + 3x?

6x

xy

5x

To simplify the expression 2x + 3x, you can combine like terms. Both terms (2x and 3x) share the same variable, x, which makes them like terms. When you combine them, you add their coefficients:

2 (from 2x) + 3 (from 3x) equals 5. Therefore, you can express the sum of these terms as 5x.

This process of combining like terms is an essential skill in algebra and allows you to simplify expressions effectively. Thus, the simplified form of 2x + 3x is indeed 5x.
