Question

52-(19+x)=17
56-(x-15)=30
(45-y)+18=58
(24+x)-21=10
(35+y)-15=31

Answer 1

52-(19+х)=17
52-19-х=17
33-х=17
-х=17-33
-х=-16
х=16
56-(х-15)=30
56-х+15=30
71-х=30
х=71-30
х=41
(45-у)+18=58
45-у+18=58
63-у=58
у=63-58
у=5
(24+х)-21=10
24+х-21=10
3+х=10
х=10-3
х=7
(35+у)-15=31
35+у-15=31
20+у=31
у=31-20
у=11
удачи :)
