5n+4 = -26 5n = -26-4 5n = -30 n = -6
5n + 3 = 14 - 6n <=> 5n +6n = 14 - 3 <=> 11n = 11 => n = 11/11 = 1
5n-25 = 10 5n = 10+25 5n = 35 n = 7
If 5n + 8 = 43, then n = 7
If 5n = 0 then n = 0, and any number of n's = 0.6n = 0
6n
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n+6=(-4) n= (-2)
5n+4=0 5n=-4 n= -4/5
5n+4 = -26 5n = -26-4 5n = -30 n = -6
5n+6=-45n=-10n=-2
The answer is 37, because you substitute n in 5 to 12 plus 5n, the answer is 37.Hope it is correct.
N=3.
5n - n = 8 + 4 ie 4n = 12 so n = 3
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5n-2+2=4n 5n=4n n=0
