Answer:

3

Step-by-step explanation:

Okay, since we know what <em>n</em> equals to, all we have to do is insert 6 where <em>n</em> was:

5(6+3)-7(6)

Now we just need to simplify, so:

30 + 15 - 42

45-42

And we get our answer

= 3

Answer:

3

Step-by-step explanation:

because if N = 6, then you will have to substitute the n to n and then do the order of operation. first it will be 6+3=9 and then 9*5=45. then you will do 7*6=42 and then subtract 45-42=3
