Реши уравнение: \((x - 5,4) \cdot 3 = 4,8 + 3,8\).

\((x - 5.4) \cdot 3 = 4.8 + 3.8\).

\(4.8 + 3.8 = 8.6\), поэтому \((x - 5.4) \cdot 3 = 8.6\).

\(x - 5.4 = 8.6 : 3 = \frac{43}{15}\).

\(x = 5.4 + \frac{43}{15} = \frac{27}{5} + \frac{43}{15} = \frac{124}{15} = 8\frac{4}{15}\).

Ответ: \(x = 8\frac{4}{15}\).
