Question

Rezolvati in Q ecuatiile: a) 5/6*(x-3 1/3*1 1/5)=2 3/4+3 3/4:1 2/3

Answer 1

$\frac{5}{6}\left(x-\frac{10}{3}\cdot \frac{6}{5}\right)=\frac{11}{4}+\frac{\frac{15}{4}}{\frac{5}{3}}$

$\frac{5}{6}\left(x-\frac{10}{3}\cdot \frac{6}{5}\right)=\frac{11}{4}+\frac{9}{4}$

$\frac{5}{6}\left(x-\frac{10}{3}\cdot \frac{6}{5}\right)=\frac{11+9}{4}$

$\frac{5}{6}\left(x-\frac{10}{3}\cdot \frac{6}{5}\right)=\frac{20}{4}$

$\frac{5}{6}\left(x-\frac{10}{3}\cdot \frac{6}{5}\right)=5$

$5\left(x-4\right)=30$

$x-4=\frac{30}{5}$

$x-4=6$

$x=6+4$

$x=10$
