3x + 1x simplifies to 4x.

When you add like terms, such as 3x and 1x (which are both terms with the variable x), you add their coefficients together. In this case, 3x + 1x is equivalent to 3 + 1 times x, which is 4x.

Answer:

4x

Step-by-step explanation:

The expression \( 3x + 1x \) simplifies to \( 4x \). This is because you can combine like terms by adding the coefficients (the numbers in front of the variables) together. So, \( 3x \) and \( 1x \) both have the variable \( x \), and their coefficients add up to 4, making the simplified expression \( 4x \).
