Question

3/7*(3-5х)-4/5*(х-3/5)=0

Answer 1

$frac{3}{7} (3-5x)- frac{4}{5} (x- frac{3}{5} )=0 \ frac{9}{7} - frac{15}{7} x- frac{4}{5} x+ frac{12}{25} =0 \ - frac{15}{7} x- frac{4}{5} x=- frac{9}{7} - frac{12}{25} \ - frac{(75+28)}{35} x=- frac{(225+84)}{175} \ - frac{105}{35} x=- frac{309}{175} \ x=- frac{309}{175} *(- frac{35}{103} ) \ x= frac{3}{5}$
