1) Реши уравнения: 1. х ∙ 5 + 125 = 750

2. 56 ∙ 70 = 8 ∙ х

3. 270 – 2х = 180

4. 1200 − х ∶ 96 = 12


​

Пошаговое объяснение:

1.

х * 5 + 125 = 750

x * 5 = 750 - 125

x * 5 = 625

x = 625 : 5

x = 125

2.

56 ∙ 70 = 8 ∙ х

3920 = 8x

x = 3920 : 8

x = 490

3.

270 – 2х = 180

2x = 270 - 180

2x = 90

x = 90 : 2

x = 45

4.

1200 − х ∶ 96 = 12

x : 96 = 1200 - 12

x : 96 = 1188

x = 1188 * 96

x = 114048
