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
Okay, since we know what n equals to, all we have to do is insert 6 where n was:
[tex]5(6+3)-7(6)[/tex]
Now we just need to simplify, so:
[tex]30 + 15 - 42[/tex]
[tex]45-42[/tex]
And we get our answer
[tex]= 3[/tex]
