Solution

To evaluate the expression 2 + 3x when x = 6, you simply substitute the value of x into the expression.

So, 2 + 3x becomes 2 + 3*6.

Then, you perform the multiplication operation first (according to the order of operations, or BIDMAS/BODMAS/PEDMAS), which gives you 2 + 18.

Finally, you perform the addition operation, which gives you 20.

So, the value of the expression 2 + 3x when x = 6 is 20.
