Step 1. Divide both sides by -4

|8 - 5n| = -13/4

Step 2. Break down the problem into these 2 equations

8 - 5n = -13/4

-(8 - 5n) = -13/4

Step 3. Solve the 1st equation: 8 - 5n = -13/4

n = 9/4

Step 4. Solve the 2nd equation: −(8 − 5n) = -13/4

n = 19/20

Step 5. Collect all solutions

n = 19/20, 9/4

Step 6. Check the solution

when n = 19/20, the original equation -4|8 - 5n| = 13 does not hold true. We will drop n = 19/20 from the solution set

Step 7. Check the solution

When n = 9/4, the original equation -4|8 - 5n| = 13 doesn't hold true either. So we will drop n = 9/4 from the solution set.

Step 8. Therefore,

No solution exists.
