Решите уравнение:
1) (x + 14) : 9 = 13;
2) 966 : (x + 17) = 23;
3) x : 8 − 6 = 49;
4) 52 + 72 : ч = 56;
5) 56 : (x − 6) = 8;
6) 56 : x − 6 = 8.
(x + 14) : 9 = 13
x + 14 = 13 * 9
x = 117 − 14
x = 103
966 : (x + 17) = 23
x + 17 = 966 : 23
x = 42 − 17
x = 25
x : 8 − 6 = 49
x : 8 = 49 + 6
x = 55 * 8
x = 440
52 + 72 : x = 56
72 : x = 56 − 52
x = 72 : 4
x = 18
56 : (x − 6) = 8
x − 6 = 56 : 8
x = 7 + 6
x = 13
56 : x − 6 = 8
56 : x = 8 + 6
56 : x = 14
x = 56 : 14
x = 4
