Реши уравнения 7*(х: 23)=560 с: 16=1273=1897 (180: у)*40=2400 26000-а=502*28

7 * (х : 23) = 560

х : 23 = 560 : 7

х : 23 = 80

х = 80 * 23

х = 1840

с : 16 + 1273 = 1897

с : 16 = 1897 - 1273

с : 16 = 624

с = 624 * 16

с = 9984

(180 : у) * 40 = 2400

180 : у = 2400 : 40

180 : у = 60

у = 180 : 60

у = 3

26000 - а = 502 * 28

26000 - а = 14056

а = 26000 - 14056 

а = 11944
