Question

Решите уравнения.

1) -(-х)+0,48= -6


2) (x-2)*(-0,1)= 5

3) дробь х/-2= дробь 4/5

Answer 1

$1) -(-x) +0,48 = -6 \ x+0,48=-6 \ x = -6-0,48 \ x = -6,48$
$2) (x-2)*(-0,1) = 5 \ x-2 = 5:(-0,1) \ x-2 = -50 \ x= -50+2 \ x=-48$
$3) frac{x}{-2} = frac{4}{5} \ x = frac{4}{5}*(-2) \ x = -frac{8}{5} \ x = -1 frac{3}{5}$
