Question

-3/7x+5/6x-8/21x=-1/49 решите плз с решением,очень прошууу

Answer 1

-3/7x + 5/6x - 8/21x = -1/49

-18/42x + 35/42x - 16/42x = -1/49

1/42x = -1/49

x = -1/49 * 42

x = -6/7

Answer 2

$- frac{3}{7} x + frac{5}{6} x - frac{8}{21} x = - frac{1}{49} \ \ - 126x + 245x - 112x = -6 \ ( - 126 + 245 - 112)x = 7x \ 7x = -6 div 7 \ x = -frac{6}{7}$
