Решите уравнение:
а) (−15) * 4x = 3 * 16 * 5;
б) −9x * 8 = 36 * (−2);
в) −24 * (−3x) = 18 * (−12);
г) (−1) * (−x) * 28 = 14 * (−16).
(−15) * 4x = 3 * 16 * 5
(−15) * 4x = 15 * 16
4x = −16
x = −4
−9x * 8 = 36 * (−2)
x * 8 = −4 * (−2)
x * 8 = 8
x = 1
−24 * (−3x) = 18 * (−12)
−24 * (−3x) = 9 * 2 * (−12)
−24 * (−3x) = 9 * (−24)
−3x = 9
x = −3
(−1) * (−x) * 28 = 14 * (−16)
x * 28 = 14 * 2 * (−8)
x * 28 = 28 * (−8)
x = −8
