Question

решите уравнение:
1. |x+3|=0
2. |1+x|=0
3. |x-3| + 0,5= 0,5

Answer 1

$|x + 3| = 0 \ x + 3 = 0 \ x = - 3 \ \ |1 + x| = 0 \ 1 + x = 0 \ x = - 1$
$|x - 3| + 0.5 = 0.5 \ x - 3 = 0.5 + 0.5 \ x - 3 = 0 \ x = 3$
Ответы: -3;-1;3

Answer 2

$1) : |x + 3| = 0 \ x + 3 = 0 \ x = - 3$
$2) : |1 + x| = 0 \ 1 + x = 0 \ x = - 1$
$3) : |x - 3| + 0,5 = 0,5 \ x - 3 = 0 \ x = 3$
