Question

Выражения 7-2x и 9x-8(x+1 ) принимают равные значения люди помогите пожалуйста

Answer 1

7-2х=9х-8(х+1)

7-2х=9х-8х-8

7-2х=х-8

-3х=-8-7

-3х=-15

х=-15/-3

х=5

Answer 2

Solving for Equal Values of Expressions

To find the values of x for which the expressions 7 - 2x and 9x - 8(x + 1) are equal, we can set them equal to each other and solve for x.

Setting the expressions equal to each other: 7 - 2x = 9x - 8(x + 1)

Solving for x: 7 - 2x = 9x - 8x - 8 7 - 2x = x - 8

Adding 2x to both sides: 7 = 3x - 8

Adding 8 to both sides: 15 = 3x

Dividing by 3: x = 5

Therefore, the value of x for which the expressions 7 - 2x and 9x - 8(x + 1) are equal is x = 5.
