Найди значение x. 3х+4/11+2 3/11=9-4 5/11 помогите плиз

Answer 1

$\displaystyle \: x = \frac{7}{11}$

Пошаговое объяснение:

$3x + \frac{4}{11} + 2 \frac{3}{11} = 9 - 4 \frac{5}{11} \\ 3x = 9 - 4 \frac{5}{11} - \frac{4}{11} - 2 \frac{ 3} {11} \\ 3x = \frac{99}{11} - \frac{49}{11} - \frac{4}{11} - \frac{25}{11} \\ 3x = \frac{21}{11} \\ x = \frac{21}{11} \div 3 \\ x = \frac{21}{11 \times 3} = \frac{7}{11}$

Answer 2

$\dfrac{7}{11}$

Пошаговое объяснение:

$3x+\dfrac{4}{11} +2\dfrac{3}{11} =9-4\dfrac{5}{11} ;\\\\3x+2\dfrac{7}{11} =8\dfrac{11}{11} -4\dfrac{5}{11} ;\\\\3x+2\dfrac{7}{11} =4\dfrac{6}{11} ;\\\\3x=4\dfrac{6}{11} -2\dfrac{7}{11};\\\\3x= 3\dfrac{17}{11}-2\dfrac{7}{11};\\\\3x=1\dfrac{10}{11} ;\\\\x=1\dfrac{10}{11} :3;\\\\x= \dfrac{21}{11} \cdot \dfrac{1}{3} ;\\\\x=\dfrac{7}{11}$
