8х − 7х + 10 = 12
x = 12 − 10 = 2
13y + 15у − 24 = 60
28y = 60 + 24 = 84
y = 84 : 28 = 3
3z − 2z + 15 = 32
z = 32 − 15 = 17
6t + 5t − 33 = 0
11t = 33
t = 33 : 11 = 3
(х + 59) : 42 = 86
(x + 59) = 86 * 42 − 3612
x = 3612 − 59 = 3553
528 : k − 24 = 64
528 : k = 64 + 24 = 88
k = 528 : 88 = 6
р : 38 − 76 = 38
p : 38 = 38 + 76 = 114
p = 114 * 38 = 4332
43m − 215 = 473
43m = 473 + 215 = 688
m = 688 : 43 = 16
89n + 68 = 9057
89n = 9057 − 68 = 8989
n = 8989 : 89 = 101
5905 − 27v = 316
27v = 5905 − 316 = 5589
v = 5589 : 27 = 207
34s − 68 = 68
34s = 68 + 68 = 136
s = 136 : 34 = 4
