(360+х) *1002 = 731460
360+х = 731460/1002
360+х = 730
х = 730-360
х=370
Проверяем:
(360+370)*1002 = 730*1002 = 731460

8д/9+1=11/3
8д/9=11/3-3/3
8д/9 = 8/3
8д = 8/3:1/9
8д = 8/3*9/1
8д = 24
д=24:8
д = 3
Проверяем:
8*3/9 +1 = 11/3
24/9+1=11/3
33/9=11/3

-5х-110 /15 = -5
-5х-110 = -5*15
-5х-110 = -75
-5х = -75+110
-5х = 35
х = 35: (-5)
х = -7
Проверяем:
-5*(-7)-110/15 = -5
35-110/15 = -5
-75/15 = -5

-4з-200/12 = -19
-4з-200= -19*12
-4з -200 = -228
-4з = -228+200
-4з = -28
з = -28:(-4)
з= 7
Проверяем:
-4*7-200/12 = -19
-28-200/12 = -228/12 = -19
