Пошаговое объяснение:
1)
8(х-16)=59,
x - 16 = 59:8
x - 16 = 7,375
x = 7,375+16
x = 23,375
2)
(45-х)*14=784,
45 - x = 784 : 14
45 - x = 56
x = 45 - 56
x = -11
3)
8(154-36х)=208,
154 - 36x = 208 : 8
154 - 36x = 26
36x = 154 - 26
36x = 128
x = 128:36
x = 3 5/9
4)
17(5х-16)=238
5x - 16 = 238 : 17
5x - 16 = 14
5x = 14+16
5x = 30
x = 30:5
x = 6
