Question

I'm confused on how to simplify variable expressions...

For example,

7x-x

and

-3p+6p

help?

Answer 1

the answer is 3p

Explanation:

Answer 2

Basically, simplifying variables is the same as regular equations (like 5-3=2 and 5x-3x=2x)

So 7x-x is the same as 7x-1x which equals 6x

And -3p+6p is the same thing as -3+6 but with a p. With this in mind, the answer is 3p

Hope this helps
