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
what does the expresstion 5n represent
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 + 10 = 10 5n = 10 - 10 5n = 0 n = 0 taylor101119: well i thought it was 5*n+5*2=10 i thought n=1 but i'm pretty sure it's the one ontop^
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

5n-2+2=4n 5n=4n n=0
-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11

8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1

3n + 2n = 25 5n = 25 n = 5
