Question

X+2x + ___=5x. What goes on the blank

Answer 1

2x

Explanation:

The equation would be x+2x+2x=5x.

You can rewrite the equation as 1x+2x+2x=5x because that is the same thing.

Then you combine all of the like terms, and because they all have an x you just add them together.

Hope this helps!
