3 answers

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.
