Решите уровнение:

1. |х+3|=0

2. |х-5|=0

3. |1+х|=0

4. |2-х|=0

5. |х-3|+0.5=0.5

6. |9+х|-0.7=0.7

1) |х+3|=0

(х-3) = 0 (х+3) = 0

х=3 х=-3

2) |х-5|=0

(х-5) = 0 (х+5) = 0

х=5 х=-5

3) |1+х|=0

(1-х) = 0 (1+х) = 0

-х=-1 |: (-1) х=-1

х=1

4) |2-х|=0

(2-х) = 0 (2+х) = 0

-х=-2 х=-2

х=2

5) |х-3|+0.5=0.5

(х-3) + 0.5=0.5 (х+3) + 0.5=0.5

х=0.5+2.5 х=0.5-3.5

х=3 х=-3

6) |9+х|-0.7=0.7

(9-х) - 0.7=0.7 (9+х) - 0.7=0.7

-х=0.7-8.3 х=0.7-8.3

х=-7.6 х=-7.6
