15з+8з-59=102

---

23з=102+59; 23з=161; з=161:23; з=7

---

9т+4т-286=0; 13т=286; т=286:13; т =22; 9*22+4*22-286=0; 192+88-286=0

Answer 1

29х-15х+16=100
14х+16=100
14х=100-16
14х=84
х=84:14
Х=6
29*6+15*6+16=100
174-90+16=100

11у+32у-127=45
43у=127+45
43у=172
У=172:43
У=4
11*4+32*4-127=45
44+128-127=45

Answer 2

15z+8z=102+59
23z=161
z=7

9t+4t=286
13t=286
t=22
