Решение:
а) 32k + k + 95 = 689:
33k + 95 = 689.
33k = 689 - 95.
33k = 594.
k = 594 / 33.
k = 18.
б) 81x - 63x + 18 = 1008:
18x + 18 = 1008.
18x = 1008 - 18.
18x = 990.
x = 990 / 18.
x = 55.
в) 24p - p + 68 = 597:
23p + 68 = 597.
23p = 597 - 68.
23p = 529.
p = 529 / 23.
p = 23.
г) 43y + 42y - 190 = 1000:
85y - 190 = 1000.
85y = 1000 + 190.
85y = 1190.
y = 1190 / 85.
y = 14.
