238 / 5 + 6n = 335 / 4
4 x 238 + 120 n = 5 x 335
952 + 120 n = 1675
120 n = 723
n = 723 / 120
n = 241 / 40
n = 24.1 / 4
n = 6.025

47 3/5 +6n= 83 3/4 lcd is 20
47 12/20+6n= 83 15/20
47 12/20-47 12/20+6n=83 15/20-47 12/20
6n=36 3/20
6n=36.15
n= 6.025

6n=83 3/4 - 47 3/5
6n= [4*83 +3] /4 - [5*47 + 3]/5
6n= 335/4 - 238/5
6n= 1675/20 - 952/20
6n= 723/20
n=723/20/6
n= 241/40 =6.025

47+(3/5)+6n = 83+(3/4)
So, here's how I work it out:
238/5 + 30n/5 = 335/4
952/20 + 120n/120 = 1675/20
120n/20 = 723/20
120n = 723
n = 6+(1/40) or 241/40

47 3/5+6n=83 3/4
or 6n=83 3/4-47 3/5
or 6n=83.75-47.6
or 6n=36.15
or n=36.15/6=6.025 ans

do you mean 47.3/5+6n=83.3/4?? where the commas are decimals?? if so then:
9.46+6n=20.825
6n=11.365
n=1.894
