[tex]1.8+7n=9.5-4n \\\\ 7n+4n=9.5-1.8 \\\\ 11n=7.7 \\\\\ \boxed{n=\frac{7.7}{11}=0.7}[/tex]

1.8+7n = 9.6 - 4n
first, you need to group the numbers with same radical, so you move 7n to the other side, and same for 9.6 (P.S., when moving a number from a side to another, you change his sign):
1.8 - 9.6 = -7n -4n
then, you calculate each side:
-7.8 = -11n
then, you found n
n= -7.8/-11
n= 0.7 (approximately) 
Hope this Helps :D
