Question 231858: is 3x+5 and 8x equivalent?
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! No
3x+5 is a variable value depending on the value of x.
---
8x is also a variable value depending on the value of x.
---
But if you let x = 5, the value of the 1st expression is 20.
The value of the 2nd expression is 40.
---
The expressions are not equivalent.
