2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
n= -2
2n-3 = 9 solve for n by first adding 3 to both sides 2n = 12 divided both sides by 2 n = 6
-17 = -2n+13-8n Subtract 13 from both sides and bring terms together: -30 = -10n Divide both sides by -10 to find the value of n which will be positive: n = 3
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2

Solve for n. 2n+3=0 2n=-3 n=-3/2
n= -2
2n-3 = 9 solve for n by first adding 3 to both sides 2n = 12 divided both sides by 2 n = 6
-17 = -2n+13-8n Subtract 13 from both sides and bring terms together: -30 = -10n Divide both sides by -10 to find the value of n which will be positive: n = 3
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
Subtract by 7x and divide by 2.
n/5 = (n+1)/3 multiply both sides by 5 n = (5n + 5)/3 multiply both sides by 3 3n = 5n + 5 subtract 3n from both sides 0 = 2n + 5 subtract 5 from both sides -5 = 2n divide both sides by 2 n = -2.5
n + 2 = 5, solve for n.n = 5 - 2n = 3
Subtract two from both sides and you are left with X equals -5
I'm assuming you are solving for n.2n + 6 = 7n - 9 {add nine to each side}2n + 15 = 7n { subtract 2n from each side}15 = 5n {divide each side by 5}3 = n
