Question

-5x-(5/18x-4)=82 срочно очень срочно помогите

Answer 1

$\displaystyle -5x-(\frac{5}{18}x-4)=82\\ \\-5x-\frac{5}{18}x+4=82\\ \\-\frac{95}{18}x+4=82\\ \\-95x+72=1476\\-95x=1476-72\\-95x=1404\\\\x=-\frac{1404}{95}=-14\frac{74}{95}$

Answer 2

$-5x-(\frac{5}{18} x-4)=82$

$-5x-\frac{5}{18} x+4=82$

$-5\frac{5}{18} x+4=82$

$-5\frac{5}{18} x=82-4$

$-5\frac{5}{18} x=78$

$x=78:(-5\frac{5}{18} )$

$78:(-5\frac{5}{18} )=-(78:\frac{95}{18})=-(\frac{78*18}{95})=-\frac{1404}{95}=-14\frac{74}{95}$

$x=-14\frac{74}{95}$

Ответ: $x=-14\frac{74}{95}$
