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

Since it is not specified what is the request of the problem, we'll simplify the given expression and we'll get:

We'll remove the brackets:

m+ n + 5m - 2

We'll re-arrange the terms and we'll combine like terms:

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

The simplified expression is:

**(m+n) + (5m-2) = 6m + n - 2**

If the request of the problem was to determine m and n, we'll solve the problem:

(m+n) + (5m-2) = 0+0

We'll put the first bracket as 0:

m + n = 0 (1)

We'll put the second bracket as zero:

5m - 2 = 0

We'll add 2 both sides:

5m = 2

We'll divide by 5:

**m = 5/2** (2)

We'll substitute m in (1):

5/2 + n = 0

We'll subtract 5/2 both sides:

**n = -5/2**

(m+n)+(5m-2) could be simpliflied.

Solution:

Open the brackets:

=m+n +5m-2

=m+5m +n -2 , as n+m = m+n by commutative law.

=6m +n-2 , m+5m = 6m as like they are like terms.

Therefore (m+n) +(5m-2) = 6m+n-2.
