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

-х=80-7.689

х=72.311

4.532+у=800•7

4.532+у=5600

у=5600-4.532

у=5595.468

х-7.321=50•5

х-7.321=250

х=250+7.321

х=257.321
