notice that both equation has a 2f term in them

solve for 2f for both eqs.

2f= 736-6n
2f= 920-10n

since they both equal to 2f, yo can set them equal to each other

736-6n = 920-10n

and solve for n if you want
6n + 2f =736
10n +2f = 920

we are going to use the bottom equation to substitute

2f = -10n +920
f = -5n +460

plug it into the first equation

6n + 2(-5n + 460) = 736
-4n + 920 =736
-4n = -184
n =46

plug into either equation, we will use the second

10(46) + 2f = 920
460 + 2f = 920
2f = 460
f = 230

FINAL ANSWER

n = 46
f = 230
