Answer 1

Ответ:

1) 8х-2х-4=8

6х=12

х=2

2) 6-2/7х=2

-2/7х=2-6

-2/7х=-4

Answer 2

Ответ:

8x-2x=8+4

6x=12

x=2

6-2/7x=2

-2/7x=2-6

-2/7x=-4

7x*(-2/7x)=-4*7x

-2=-28x

x=2/28

x=1/14

Answer 3

a) To solve the equation 8x - 2x - 4 = 8, follow these steps:

Step 1: Combine like terms on the left side. 6x - 4 = 8

Step 2: Move the constant term to the right side by adding 4 to both sides. 6x = 12

Step 3: Isolate x by dividing both sides by 6. x = 12 / 6 x = 2

The solution to the equation is x = 2.

б) To solve the equation 6 - (2/7)x = 2, follow these steps:

Step 1: Move the constant term to the right side by subtracting 6 from both sides. -(2/7)x = 2 - 6 -(2/7)x = -4

Step 2: To isolate x, multiply both sides by -7/2 (the reciprocal of -2/7). x = (-4) * (-7/2) x = 28/2 x = 14

The solution to the equation is x = 14.
