Question

2) 3 1/6х + 1/3х = 7 1/4 помогите пожалуйста решить

Answer 1

$3 \frac{1}{6} x + \frac{1}{3} x = 7 \frac{1}{4} \\ 3 \frac{1}{6} x + \frac{1}{3} x = 3 \frac{1}{6} + \frac{2}{6} = 3 \frac{3}{6} = 3 \frac{1}{2}$
$3 \frac{1}{2} x = 7 \frac{1}{4} \\ x = 7 \frac{1}{4} \div 3 \frac{1}{2} = \frac{29}{4} \times \frac{2}{7} = \frac{29}{14} =$
$= 2 \frac{1}{14}$
