    x = 12

    Step-by-step explanation:

    Simplifying

    6x + - 2 (-3x + - 5) = 154

    Reorder the terms:

    6x + - 2 (-5 + - 3x) = 154

    6x + (-5 * - 2 + - 3x * - 2) = 154

    6x + (10 + 6x) = 154

    Reorder the terms:

    10 + 6x + 6x = 154

    Combine like terms: 6x + 6x = 12x

    10 + 12x = 154

    Solving

    10 + 12x = 154

    Solving for variable 'x'.

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

    Add '-10' to each side of the equation.

    10 + - 10 + 12x = 154 + - 10

    Combine like terms: 10 + - 10 = 0

    0 + 12x = 154 + - 10

    12x = 154 + - 10

    Combine like terms: 154 + - 10 = 144

    12x = 144

    Divide each side by '12'.

    x = 12

    Simplifying

    x = 12
