    4n - 8 = n + 1

    Solve for n in the equation 4n - 8 = n + 1

    Step 1: Group variables:
    We need to group our variables 4n and n. To do that, we subtract n from both sides
    4n - 8 - n = n + 1 - n

    Step 2: Cancel n on the right side:
    3n - 8 = 1

    Step 3: Group constants:
    We need to group our constants -8 and 1. To do that, we add 8 to both sides
    3n - 8 + 8 = 1 + 8

    Step 4: Cancel 8 on the left side:
    3n = 9

    Step 5: Divide each side of the equation by 3
    3n/3 = 9/3

    n = 3
