Whatever your value of n is, you need to multiply it by 5 and then add 2 to get your answer. Below is how to solve it algebraically: 5n+2 = 0 (it needs to be equal to something in order to solve it, so I assumed that it equals zero) 5n = -2 n = -2/5
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
(3n+2)(n+1)
3n+2+3n+2=6n+4
3
It is the same as: 30n^2 +36n
6n = 12 n = 2
5n-2+2=4n 5n=4n n=0
5n+6=(-4) n= (-2)
5n - 4 = 10n + 6-5n = 10n = -2
5n+6=-45n=-10n=-2
4n
5n+15 = 25 5n = 25-15 5n = 10 n = 2
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
22n + 2.
n=1 2/3
