Решите уравнения. x*5+796=1021, 859+x:6=1224, x-2095=304*80

1 ) x * 5 + 796 = 10215 * х = 1021 – 796 = 1000 + 21 – 700 – 96 = 300 + 21 – 96 = 4 + 21 = 25 5 * х = 25 х = 25 / 5 х = 5 Проверка 5 * 5 + 796 = 1021 25 + 796 = 1021 1021 = 1021 ВерноОтвет: х = 5 2 ) 859 + x : 6 = 1224 х / 6 = 1224 – 859 = 1000 + 224 – 800 – 59 = 200 + 224 – 59 = 141 + 224 = 365х / 6 = 365х / 6 = 365 / 1 х = 365 * 6 = 300 * 6 + 60 * 6 + 5 * 6 = 1800 + 360 + 30 = 2190 х = 2190Проверка 859 + 2190 / 6 = 1224 859 + 365 = 1224 1224 = 1224 ВерноОтвет: х = 21903 ) x – 2095 = 304 * 80х - 2095 = 24320 х = 24 320 + 2095 х = 26415Проверка 26415 – 2095 = 24 320 24 320 = 24320 ВерноОтвет: х = 26 415
