2. Решим уравнения, чтобы найти неизвестные числа.
$$x \, \cdot \, 7 = 14 \, 525.4$$
$$x = 14 \, 525.4 \, : \, 7$$
$$x = 2075.06$$
$$y \, \cdot \, 9 = 54 \, 324 \, : \, 6$$
$$y \, \cdot \, 9 = 9054$$
$$y = 9054 \, : \, 9$$
$$y = 1006$$
$$z \, \cdot \, 3 = 6030.5$$
$$z = 6030.5 \, : \, 3$$
$$z = 2010.1(6)$$
$$u \, \cdot \, 9 = 90 \, 652 - 83 \, 407$$
$$u \, \cdot \, 9 = 7245$$
$$u = 7245 \, : \, 9$$
$$u = 805$$
$$v \, \cdot \, 6 = 76 \, 620 + 47 \, 580$$
$$v \, \cdot \, 6 = 124 \, 200$$
$$v = 124 \, 200 \, : \, 6$$
$$v = 20 \, 700$$
$$w \, \cdot \, 4 = 100 \, 000 - 91 \, 720$$
$$w \, \cdot \, 4 = 8280$$
$$w = 8280 \, : \, 4$$
$$w = 2070$$
Ответ: x = 2075.06; y = 1006; z = 2010.1(6); u = 805; v = 20 700; w = 2070
