5-2n=3
-2n=3-5
-2n=-2
n=1
2n/3 = 4 2n = 3*4 2n = 12 n = 6 :)
2n-3 = 9 solve for n by first adding 3 to both sides 2n = 12 divided both sides by 2 n = 6
n= -2
-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
-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
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
Subtract by 7x and divide by 2.
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
To solve the equation (10n = 36 - 2n), first, add (2n) to both sides to get (10n + 2n = 36), which simplifies to (12n = 36). Next, divide both sides by 12 to isolate (n), resulting in (n = 3). Thus, the solution to the equation is (n = 3).
