    Simplifying

    x = 11

    Step-by-step explanation:

    Simplifying

    6x + - 27 = 39

    Reorder the terms:

    -27 + 6x = 39

    Solving

    -27 + 6x = 39

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '27' to each side of the equation.

    -27 + 27 + 6x = 39 + 27

    Combine like terms: - 27 + 27 = 0

    0 + 6x = 39 + 27

    6x = 39 + 27

    Combine like terms: 39 + 27 = 66

    6x = 66

    Divide each side by '6'.

    x = 11

    Simplifying

    x = 11
