Question

3*(х-4 1/3)+1 1/6=-3‚5 решите пожалуйста​

Answer 1

$3(x - \frac{13}{3} ) + 1\frac{1}{6} = - 3.5$

$3x - 13 + 1 \frac{1}{6} = - 3.5$

$3x - 13 + \frac{7}{6} = - 3.5$

$3x - \frac{71}{6} = - 3.5$

$3x = - \frac{7}{2} + \frac{71}{6}$

$3x = \frac{25}{3}$

$x = \frac{25}{3} \div 3 = \frac{25}{3} \times \frac{1}{3}$

$x = \frac{25}{9}$

$x = 2 \frac{7}{9}$

Answer 2

3х-12 3/3+1 1/6 = -3,5

3х+1 1/6 = 13-3,5

3х = 9,5-7/6

3х = 50/6

х = 2 7/9

Ответ: 2 7/9
