Step-by-step explanation:
Since we have common denominators inside the parentheses, we can combine the denominators. Then, we get the following expression:


Now, we can multiply the expression inside the parentheses by 2.

Since the expression inside the parentheses cannot be <u>simplified further</u>, we can open the parentheses and simplify the expression.

We can combine the denominators as the denominators are the same.

Finally, we can simplify -4 + 3.

Therefore, the simplified expression is (2m - 1)/5.
