Реши уравнения, выполни проверку 7.689 - x = 560 / 7 4.532 + y = 800 x 7 x - 7.321 = 60 x 5

7689 - Х = 560 : 7
7689 - Х = 80
Х = 7689 - 80
Х = 7609
7689 - 7609 = 560 : 7
80 = 80.

4532 + Y = 800 * 7
4532 + Y = 5600
Y = 5600 - 4532
Y = 1068
4532 + 1068 = 800 * 7
5600 = 5600.

Х - 7321 = 60 * 5
Х - 7321 = 300
Х = 7321 + 300
Х = 7621
7621 - 7321 = 60 * 5
300 = 300.

7.689-х=560/7
7.689-х=80
