Question

2х+2х+2+2х+4+2х-6=-20

Answer 1

2х+2х+2+2х+4+2х-6=-20

2х+2х+2х+2х=-20-2-4+6

8х=-20

х=-20/8

х=-2,5

Ответ: -2,5

Answer 2

Let's solve the equation step by step:

2x + 2x + 2 + 2x + 4 + 2x - 6 = -20

Combining like terms on the left side:

8x + 2 = -20

Subtracting 2 from both sides:

8x = -20 - 2

8x = -22

Dividing both sides by 8:

x = -22/8

Simplifying the fraction:

x = -11/4

Therefore, the solution to the equation is x = -11/4.
