Решите уравнение z+34=50
(36+y)-18=33
703+(346-y)=924

z + 34 = 50

z = 50 - 34

z = 16

________________

( 36 + y ) - 18 = 33

36 + y = 33 + 18

36 + y = 51

y = 51 - 36

y = 15

_______________

703 + ( 346 - y ) = 924

346 - y = 924 - 703

346 - y = 221

y = 346 - 221

y = 125

________________

з+34=50

з=50-34

з=16

2)(36+у)-18=33

у-18=36-33

у-18=3

у=18+3

у=21

3)703+(346-у)=924

703-у=924-346

703-у=578

у=703-578

у=125
