Question

1) 10x+3 (7-2x)=13+2x​

Answer 1

10x+3(7-2x)=13+2x;

10х+21-6х=13+2х

10х-6х-2х=13-21

2х=-8

х=-4

Answer 2

Ответ:

x = 4

Объяснение:

Умножьте каждое слагаемое на множитель 3 и раскройте скобки

10x+21-6x=13+2x

Сведите подобные слагаемые

10x+21-6x=13+2x

Перенесите слагаемые

4x+21-13+2x

Сведите подобные слагаемые и вычислите

4х-2х-13-21

Разделите обе части

2x= -8

ответ : х = 4

Answer 3

To solve the equation 10x + 3(7 - 2x) = 13 + 2x, follow these steps:

1. Distribute the 3 on the left side of the equation: 10x + 21 - 6x = 13 + 2x

2. Group like terms on both sides of the equation: (10x - 6x - 2x) + 21 = 13

3. Combine like terms: 2x + 21 = 13

4. Subtract 21 from both sides to isolate the x terms: 2x = 13 - 21 2x = -8

5. Finally, divide both sides by 2 to solve for x: x = -8 / 2 x = -4

So, the solution to the equation is x = -4.
