Answer:
5x + 30
Explanation:
Like terms are the terms that carry the same variable.
Here, 2x, 4x, and -x all have an x of degree 1. So, they are like terms. Thus, we can combine these into: 2x + 4x - x = 5x.
Now, -5, 29, and 6 are like terms because they are all constants, or non-variables. So, we can combine these: -5 + 29 + 6 = 30
Thus, the answer is 5x + 30.
Hope this helps!
