Question

уравнение : 
    $frac{5}{2} x+ frac{5}{3} x+ frac{5}{6} x= frac{15}{1001}$

Answer 1

$frac{5}{2}x + frac{5}{3}x+ frac{5}{6}x = frac{15}{1001}\\ frac{5*3x+5*2x+5x}{6} = frac{15}{1001}\\ frac{15x+10x+5x}{6}= frac{15}{1001} \\ frac{30x}{6} = frac{15}{1001} \\5x= frac{15}{1001}\\x= frac{15}{1001}:5\\x= frac{15}{5*1001} \\x= frac{3}{1001}$
