    2n + 10 = 3n + 5

    Solve for n in the equation 2n + 10 = 3n + 5

    Step 1: Group variables:
    We need to group our variables 2n and 3n. To do that, we subtract 3n from both sides
    2n + 10 - 3n = 3n + 5 - 3n

    Step 2: Cancel 3n on the right side:
    -n + 10 = 5

    Step 3: Group constants:
    We need to group our constants 10 and 5. To do that, we subtract 10 from both sides
    -n + 10 - 10 = 5 - 10

    Step 4: Cancel 10 on the left side:
    -n = -5

    Step 5: Divide each side of the equation by -1
    -1n/-1 = -5/-1

    n = 5
