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+15 = 25 5n = 25-15 5n = 10 n = 2
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
5n-5, because its the 5 time table (called 5n) minus 5 each time
5n-25 = 10 5n = 10+25 5n = 35 n = 7
5n-2+2=4n 5n=4n n=0
In the equation 5n-11=4n+20, n is equal to 31.
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
4 over 5n
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
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.

5n - 9 = 2n + 6 : Add 9 to both sides 5n = 2n + 15 : Subtract 2n from both sides 3n = 15 : Divide both sides by 3 n = 5
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
Add 1 to both sides, so 5n is 8. So now divide both sides by 5, and so n=8/5
It is: minus five multiplied by n = -5n
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
Well, first you add 7 to 38, which is 45, then divide by 5, therefore n=9.
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
