(2m−3)+(3n−1)+(3m+1).

2m - 3 + 3n - 1 + 3m + 1

Combine like terms:

(2m + 3m) + (3n) + (-3 - 1 + 1)

5m + 3n - 3

The simplified expression is 5m + 3n - 3.

2(10b+4)−(b−2).

2(10b + 4) - (b - 2)

Distribute the 2 to both terms inside the first parentheses:

20b + 8 - (b - 2)

Remove the second set of parentheses:

20b + 8 - b + 2

Combine like terms:

(20b - b) + (8 + 2)

19b + 10

The simplified expression is 19b + 10.

To simplify the expression (2m−3)+(3n−1)+(3m+1), you can combine like terms.

First, let's combine the m terms: 2m + 3m = 5m.

Next, let's combine the constant terms: -3 + 1 + 1 = -1.

Now, substitute these simplified terms back into the expression:

5m + 3n - 1

Therefore, the simplified expression is 5m + 3n - 1.

To simplify the expression (2m−3)+(3n−1)+(3m+1), we first need to combine like terms.

Like terms are terms that have both the same variable and exponent. In this case, the variables are m and n.

Let's group the like terms together:

(2m + 3m) + (-3 + 1) + (3n)

Since 2m and 3m have the same variable and exponent, we can combine them:

5m + (-3 + 1) + 3n

Now, let's simplify the expression further by adding the numbers:

5m - 2 + 3n

So, the simplified expression is 5m - 2 + 3n.
