$- 8x + 23x - x = - 8x + 23x -1x = ( - 8 + 23 - 1)x = 14x.$

Подставим при х=3/14.

$14 \cdot \dfrac{3}{14} = 3.$

Пошаговое объяснение:

-8х+23х-х = -9х + 23х = 14х = 14 • 3/14 = 3

Answer 3

To evaluate the expression -8x + 23x - x when x = 3/14, we substitute the value of x into the expression and simplify:

-8(3/14) + 23(3/14) - (3/14)

To simplify, we first perform the multiplications:

-24/14 + 69/14 - 3/14

Next, we combine the fractions with a common denominator:

(-24 + 69 - 3) / 14

Simplifying the numerator:

42/14

Finally, we simplify the fraction:

3

Therefore, when x = 3/14, the expression -8x + 23x - x equals 3.
