From the expression 2x+4, replace x by 5 as we get:

Step 2
Simply evaluate by multiplying 2*5 then add in 4.

Hence, the solution is 14.
Additional Information:
- The evaluated value is the value of y-term at specific domain (x = 5). That means when x = 5, the value of y would be 14. This is pretty useful on Functions and Graphs lesson.
