It is an equation and the value of n is 9.1
In the equation 5n-11=4n+20, n is equal to 31.
Represent the number by n. The equation is 5n - 1 = 3n +5, and the solution is n = 3.
5n=30n=30/5n=6
Add 1 to both sides, so 5n is 8. So now divide both sides by 5, and so n=8/5
It is an equation and the value of n is 9.1
In the equation 5n-11=4n+20, n is equal to 31.
Represent the number by n. The equation is 5n - 1 = 3n +5, and the solution is n = 3.
The solution set is x = 5n + 3 where n is any integer.
what does the expresstion 5n represent
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=30n=30/5n=6
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.
Add 1 to both sides, so 5n is 8. So now divide both sides by 5, and so n=8/5
5n+4 = -26 5n = -26-4 5n = -30 n = -6
5n-25 = 10 5n = 10+25 5n = 35 n = 7
5n - 4 = 10n + 6-5n = 10n = -2
