Question

What is the sum of (2n – 5m) and (n + m)?

Answer 1

3n - 4m

Explanation:

(2n – 5m) and (n + m) in this case have the same value if the parentheses are removed. We end up with:

2n – 5m

n + m

-------------- Grouping like terms vertically, as shown here, may make this

addition a bit easier.

2n – 5m

n + m

--------------

3n - 4m (final answer)

Answer 2

3n - 4m

Explanation:

(2n-5m)+(n+m)

so we get this equation and from here, we expand the equation by removing the brackets, you should get:

2n-5m+n+m and just solve from here.

to make it easier, put the like terms together:

2n+n+m-5m

= 3n-4m
