    Step-by-step explanation:

    Simplifying

    (14x + 70) = (20x + 8)

    Reorder the terms:

    (70 + 14x) = (20x + 8)

    Remove parenthesis around (70 + 14x)

    70 + 14x = (20x + 8)

    Reorder the terms:

    70 + 14x = (8 + 20x)

    Remove parenthesis around (8 + 20x)

    70 + 14x = 8 + 20x

    Solving

    70 + 14x = 8 + 20x

    Solving for variable 'x'.

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

    Add '-20x' to each side of the equation.

    70 + 14x + - 20x = 8 + 20x + - 20x

    Combine like terms: 14x + - 20x = - 6x

    70 + - 6x = 8 + 20x + - 20x

    Combine like terms: 20x + - 20x = 0

    70 + - 6x = 8 + 0

    70 + - 6x = 8

    Add '-70' to each side of the equation.

    70 + - 70 + - 6x = 8 + - 70

    Combine like terms: 70 + - 70 = 0

    0 + - 6x = 8 + - 70

    -6x = 8 + - 70

    Combine like terms: 8 + - 70 = - 62

    -6x = - 62

    Divide each side by '-6'.

    x = 10.33333333

    Simplifying

    x = 10.33333333
