Answer:
3x
Explanation:
If you have 2x, that would mean there is 1x and 1x. T
he question asks what 2x+2x+1x is, and since all three have the same variable you can just add the coefficient.
The coefficients are 1, 1, and 1 since they are in front of the variable.
The variable is x.
Therefore, since 1+1+1=3, your answer is 3x.
