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

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
22n + 2.
n=1 2/3
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
