    Answer: - 5.6

    Step-by-step explanation:

    Simplifying

    (4x + - 28) = 9x

    Reorder the terms:

    (-28 + 4x) = 9x

    Remove parenthesis around (-28 + 4x)

    -28 + 4x = 9x

    Solving

    -28 + 4x = 9x

    Solving for variable 'x'.

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

    Add '-9x' to each side of the equation.

    -28 + 4x + - 9x = 9x + - 9x

    Combine like terms: 4x + - 9x = - 5x

    -28 + - 5x = 9x + - 9x

    Combine like terms: 9x + - 9x = 0

    -28 + - 5x = 0

    Add '28' to each side of the equation.

    -28 + 28 + - 5x = 0 + 28

    Combine like terms: - 28 + 28 = 0

    0 + - 5x = 0 + 28

    -5x = 0 + 28

    Combine like terms: 0 + 28 = 28

    -5x = 28

    Divide each side by '-5'.

    x = - 5.6

    Simplifying

    x = - 5.6
