Question

How do you evaluate `9p - 5q + 9- 5p + 5q - 6`?

Answer 1

We must collect like terms and simplify: See below

Explanation:

We must first take into consideration the variables and constants within the expression.

We have a `p`, `q` and a normal number (constant).

Now we collect like terms and simply:

`9p-5p = 4p`
`-5q+5q=0`
`9-6=3`

Now we literally we put the terms together:

`therefore` final answer `=4p+3`
