    n = 42

    Step-by-step explanation:

    Given expression is: 3 (n-5) - 2 (n+8) = 11

    Now, first of all we will multiply the numbers which are outside the brackets to the numbers inside. Which will become:

    3n-15 - 2n - 16 = 11

    Next the second step is to the change the positions. The numbers that are multiplied by n will be together:

    3n - 2n - 15 - 16 = 11

    Finally, by solving the above equation. We get:

    n - 31 = 11

    n = 11 + 31

    n = 42

    Required answer is n = 42

    n=42

    Step-by-step explanation:

    The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:

    3n-15-2n-16=11

    Then we collect like terms together.

    3n-2n-15-16=11

    evaluating the above equation we get

    n-31=11

    n=11+31

    =42
