Question

3 1/8х - (3,5-2х)=3 * (2 5/6 +1 1/3х) з поясненням будь ласка​

Answer 1

Ответ:

$x = 10 \dfrac{2}{3}$

Пошаговое объяснение:

$\displaystyle 3 \frac{1}{8 }x - ( 3,5 -2x ) = 3 \cdot \bigg (2\frac{5}{6} + 1\frac{1}{3}x \bigg ) \\\\\\ 3 \frac{1}{8} x - 3,5 +2x = 3\cdot \bigg ( \frac{17}{6} + \frac{4}{3}x \bigg ) \\\\\\ 5 \frac{1}{8}x - 3,5 = 8,5 + 4x \\\\\\ 5\frac{1}{8}x - 4x = 8,5 + 3,5 \\\\\\ 1\frac{1}{8} x = 12 \\\\\\ \frac{9}{8} x = 12 \\\\\\ x = \frac{8}{9} \cdot 12 = \frac{32}{3} = 10 \frac{2}{3}$

Answer 2

Ответ:

10. 2/3

Пошаговое объяснение:

3. 1/8х - (3,5 - 2х) = 3 * (2. 5/6 + 1. 1/3х)

3. 1/8х - 3. 5/10 + 2х = 3 * (17/6 + 4/3х)

3. 1/8х - 3. 1/2 + 2х = 51/6 + 12/3х

5. 1/8х - 3. 1/2 = 8. 3/6 + 4х

5. 1/8х - 4х = 8. 3/6 + 3. 1/2

1. 1/8х = 8. 1/2 + 3. 1/2

1. 1/8х = 11. 2/2

9/8х = 12

х = 12 : 9/8

х = 12 * 8/9

х = 4 * 8/3

х = 32/3

х = 10. 2/3
