    Let me tell you ...

    This equation cannot be solved at all.

    Why?

    3 (n+5) ≥3n+8

    3n+15 ≥ 3n+8

    3n-3n ≥ 8-15

    0 ≥ - 7

    Even though it make sense than 0 ≥ - 7 ... But since 'n' disappeared, this means that this equation have no solution. To solve means to find the value of 'n' and if there is no 'n' since 3n-3n=0, there is no solutions.

    This question is pretty much invalid.

    Extra:

    To tackle such inequality qns:

    Step 1: Expand the brackets

    Step 2: Move the term to one side of the equations

    and constant to another side of the equation.

    Step 3: Find the value of the term. Done.
