Answer:
2n - 5
Step-by-step explanation:
Pre-Solving
We are given that A is -3n + 2 and B is 5n - 7.
We want to find the value of A + B in its simplest form
Finding it in its simplest form means we combine all of the like terms together.
Solving
We can replace A with -3n + 2 and B with 5n -7
A + B => -3n + 2 + 5n - 7
Combine the terms with n together.
-3n + 5n = 2n
Combine the numbers together.
2 - 7 = -5
Now, add 2n and -5 together.
2n + -5
This can be simplified to be:
2n - 5
This expression can't be simplified anymore, so this means that 2n - 5 is its simplest form.
