Пользуясь формулой a = b * c + r, найди:
1) a, если b = 6, c = 8, r = 4;
2) b, если a = 29, c = 3, r = 2;
3) c, если a = 38, c = 7, r = 3;
4) b, если a = 59, c = 6, r = 5.
a = b * c + r
a = 6 * 8 + 4
a = 48 + 4
a = 52
a = b * c + r
b * c = a − r
b = (a − r) : c
b = (29 − 2) : 3
b = 27 : 3
b = 9
a = b * c + r
b * c = a − r
c = (a − r) : b
c = (38 − 3) : 7
c = 35 : 7
c = 5
a = b * c + r
b * c = a − r
b = (a − r) : c
b = (59 − 5) : 6
b = 54 : 6
b = 9
