9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
(m - 5)(n - 4)
Subract 5n from both sides and you get 9=-3n, then divide bother sides by -3 and you get n= -3
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
If 5n + 8 = 43, then n = 7
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
5n+15 = 25 5n = 25-15 5n = 10 n = 2
It is 5n + 9r.
5n+4 = -26 5n = -26-4 5n = -30 n = -6
6n
The answer is 37, because you substitute n in 5 to 12 plus 5n, the answer is 37.Hope it is correct.
5n+4=0 5n=-4 n= -4/5
(2n+3)(n+1)=2n2+5n+3.
5n+6=(-4) n= (-2)
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
5n - n = 8 + 4 ie 4n = 12 so n = 3
