2у+7у+78= 1581
9у = 1581 - 78
9у= 1503
у= 1503/9
у= 167
проверим:
2 * 167 + 7 * 167 + 78 = 1581
167 *(2+7) + 78 = 1581
167 * 9 + 78 = 1581
1503 + 78 = 1581
1581=1581
256m - 147m - 1871 = 63747
109m = 63747 + 1871
109m=65618
m= 65618 /109
m=602
проверим:
256 * 602 - 147 * 602 - 1871 = 63747
154112 - 88494 - 1871= 63747
154112-90365=63747
63747=63747
