Question

5 1/4х-2 2/3=1 5/12 помогите решить

Answer 1

$5 \frac{1}4} x-2 \frac{2}{3} =1 \frac{5}{12} \\ \frac{21}{4} x- \frac{8}{3} = \frac{17}{12} \\ \frac{21}{4} x= \frac{17}{12} + \frac{8}{3} \\ \frac{21}{4} x= \frac{49}{12} \\ x= \frac{49}{12} : \frac{21}{4} \\ \boxed{\bold{x= \frac{7}{9}}} .$
