(n-5) + 8 = 23
subtract 8 from both sides so you end up with:
n-5 = 15
add 5 to both sides
n=20

To find the value of n, what number -5 + 8 = 23. Subtract 5 from 8 =3 now subtract 5 from 23 = 17 now add the 3 to 17 =20 so n=(20 -5) + 8 = 23. 5 subtracted from 20 = 15 +8 =23

The parenthesis are not needed in this problem so you can drop them and then add -5 and +8 together.
(n-5)+8 = 23
n-5+8 = 23
n+3 = 23 (-5+8 = +3)
n+3-3 = 23-3 (subtract 3 from each side)
n = 20.
Hope this helps. Good Luck.

It's the same as n-5+8=23
n+3=23
n=20

(n-5)+8=23
(n-5)+8-8=23-8
(n-5)=15
n-5+5=15+5
n=20
hope this helps. do the same action to each side, what is in brackets is one unit, and is done separate from the rest of the equation.

15+8 is 23 so (n-5) is 15. 20-5=15 so....... n=20.
