step 1= transpose 1/8 to the other side by subtracting 1/8 on both sides
-5n/8+1/8-1/8=1/2-1/8
5n/8=3/8
step 2= divide both sides by 8 to eliminate the denominator
8(5n/8=3/8)8
5n=3
step 3= divide 5 to get the value of n
5n/5=3/5
n=3/5
to check: substitute the value...if it yields the an equal answer to the given equation...then it's correct...good luck!

8(5n/8 + 1/8) = 8(1/2)
5n + 1 = 4
- 1 - 1
5n = 3
5n/5 = 3/5
n = 3/5

5n/8 + 1/8 = 1/2
Step 1: get 5n/8 alone by subtracting 1/8 from both sides:
5n/8 + 1/8 - 1/8 = 1/2 - 1/8
5n/8 = 3/8
Step 2: Multiply both sides by 8/5 to get n alone.
5n/8 * 8/5= 3/8 * 8/5
n = 3/5 (solution!)

5n/8 +1/8=1/2
8(5n/8 +1/8)=1/2 * 8
5n+1 =4
5n+1 -1=4-1
5n=3
5n/5=3/5
n=3/5

I'll start you out...
(5n+1)/8 = 1/2
The next thing you want to do is get that 5n+1 by itself on one side of the equals sign. What do you need to do to both sides of the equation to do that?

hi
(5n+1)/8=1/2
2(5n+1)=8
5n+1=8/2
5n+1=4
5n=4-1
5n=3
n=3/5
3/5=0.6
5*0.6/8+1/8=1/2
3/8+1/8=1/2
(3+1)/8=1/2
4/8=1/2
1/2=1/2
