Решите уравнения: 1) 570 * X - 4700 = 13540; 2) 340 * X - 416 * 2 = 18208; 3) (223440 - 130 * X) : 35 = 6020; 4) (31 * 550 - X) * 120 = 10200.

1) \(570 \cdot X - 4700 = 13540\)

\(570X = 13540 + 4700\)
\(570X = 18240\)
\(X = 18240 : 570\)
\(X = 32\)

2) \(340 \cdot X - 416 \cdot 2 = 18208\)

\(416 \cdot 2 = 832\)
\(340X - 832 = 18208\)
\(340X = 19040\)
\(X = 56\)

3) \((223440 - 130 \cdot X) : 35 = 6020\)

\(223440 - 130X = 6020 \cdot 35\)
\(223440 - 130X = 210700\)
\(130X = 223440 - 210700\)
\(130X = 12740\)
\(X = 98\)

4) \((31 \cdot 550 - X) \cdot 120 = 10200\)

\(31 \cdot 550 = 17050\)
\((17050 - X) \cdot 120 = 10200\)
\(17050 - X = 85\)
\(X = 16965\)

Ответ: \(1)\ X=32;\ 2)\ X=56;\ 3)\ X=98;\ 4)\ X=16965\).
