Subtract. Write the difference in simplest form. (5n - 3) - (-2n + 7)

A. 7n - 10

B. 3n + 4

C. 3n - 10

D. 7n + 4

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

Then all you have to do is combine the like terms, so

5n+2n=7n and - 3 + (-7) = - 10

And the answer is A. 7n-10

To subtract (5n - 3) - (-2n + 7), you must take in consideration the minus sign before the second group. To get rid of it, you need to multiply the second group by - 1.

So, you would get something like this:

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

Now, add the two groups:

5n - 3 + 2n - 7 = 7n - 10

So, your answer would be:

A. 7n - 10
