Subtract. Write the difference in simplest form.

(5n - 3) - (-2n + 7)

3 n - 10

7 n + 4

3 n + 4

7 n - 10

7n - 10

Step-by-step explanation:

Whenever we have a "-" in front of an expression, the expression's signs change. For example:

- (a - b) = - a + b

The last part of the expression is:

- (-2n + 7) Which will be

2n - 7

So, we now have:

(5n - 3) + (2n - 7)

We can take away the parenthesis, so we have:

5n - 3 + 2n - 7

We add up the variables and the numbers and have:

5n + 2n = 7n

-3 - 7 = - 10

Our answer is

7n - 10

The last answer choice is right.
