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

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