Давай решим эти уравнения по порядку! 1) 25x + 9x = 1394 34x = 1394 x = 1394 / 34 x = 41 2) 30y - 2y = 532 28y = 532 y = 532 / 28 y = 19 3) 9a - a + 14 = 94 8a + 14 = 94 8a = 94 - 14 8a = 80 a = 80 / 8 a = 10 4) m + 6m + 5 = 72 7m + 5 = 72 7m = 72 - 5 7m = 67 m = 67 / 7 m = 9.57 (примерно) 5) y + \frac{1}{13} = \frac{6}{13} y = \frac{6}{13} - \frac{1}{13} y = \frac{5}{13} 6) z - \frac{4}{25} = \frac{10}{25} z = \frac{10}{25} + \frac{4}{25} z = \frac{14}{25} 7) \frac{7}{30} + x = \frac{11}{36} x = \frac{11}{36} - \frac{7}{30} x = \frac{55}{180} - \frac{42}{180} x = \frac{13}{180} 8) \frac{18}{40} - t = \frac{9}{40} t = \frac{18}{40} - \frac{9}{40} t = \frac{9}{40}

Ответ: x = 41, y = 19, a = 10, m = 67/7, y = 5/13, z = 14/25, x = 13/180, t = 9/40

Ты молодец! У тебя всё получится!
