Add 1 to both sides, so 5n is 8. So now divide both sides by 5, and so n=8/5
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n-2+2=4n 5n=4n n=0
It is an equation and the value of n is 9.1
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
To solve the equation 5n - 7 = 38, do whatever you do to one side of the equals sign to the other. So, add 7 to both sides. 5n = 38. Now divide both sides by 9. 5 = 9. To check your answer, replace the n with 9 and solve the equation. 5 x 9 - 7 = 38. Do the multiplacation first. 45 - 7 = 38. 38 = 38. The answer is correct.
9-5n+1 = 15 -5n = 15-9-1 -5n = 5 Divide both sides of the equation by -5 to find the value of n: n = -5
5n-25 = 10 5n = 10+25 5n = 35 n = 7
Add 1 to both sides, so 5n is 8. So now divide both sides by 5, and so n=8/5
5n+15 = 25 5n = 25-15 5n = 10 n = 2
5n-2+2=4n 5n=4n n=0
It is an equation and the value of n is 9.1
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
Previous poster was very wrong, 5n-3=17 5n=20 n=4
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
5n-3
In the equation 5n-11=4n+20, n is equal to 31.
