34х + 17х= 1173 (23n + n + 80) 10 = 170000
51х = 1173 24n + 80 = 170000 : 10
х = 1173 : 51 24n = 17000 - 80
х = 23 24n = 16920
n = 16920 : 24
n = 705
48у - 25у - 20 = 417 (5k +3k + 7k) : 10 = 1203
23у = 417 +20 15k = 1203 * 10
у = 437 : 23 15k = 12030
у = 19 k = 12030 : 15
k = 802
7t + t + 27 = 99 (2h + 8h) 17 = 1700
8t = 99 - 27 10h = 1700 : 17
8t = 72 10h = 100
t = 72 : 8 h = 100 : 10
t = 9 h = 10
15z - z - 16 = 96 (16f - 12f + f) : 25 = 5
14z = 96 + 16 5f = 5 * 25
14z = 112 5f = 125
z = 112 : 14 f = 125 : 5
z = 8 f = 25
(4s + s + 6s) : 7 = 11 6m + 4m + 15 = 375
11s = 11 * 7 10m = 375 - 15
11s = 77 10m = 360
s = 77 : 11 m = 360 : 10
s = 7 m = 36
