Final answer:
The value of 1x+2x when x=2 is calculated by combining like terms to get 3x and then substituting x with 2 to obtain 6.
Step-by-step explanation:
The question asks what is the value of 1x+2x when x=2. To find the value, follow these steps:
Combine like terms: 1x and 2x are both terms with x, so you can add them to get 3x.
Substitute the value of x: Now, replace x with 2 in the expression 3x to get 3(2).
Calculate the expression: Multiplying 3 by 2 gives you 6.
Therefore, the value of 1x+2x when x=2 is 6.
