Решить уравнения:
1) х+5,2= - 7,1 2) -3,4 – х=2,8 3) 15,7 + х = 11,35
4) – 8,82 + х = - 9,54 5) 6,73 – х = - 10,58 6) -12,48 – х = - 5,28 7) х – 5,52 = - 8,24

1) x + 5.2 = -7.1

x + 5.2 - 5.2 = -7.1 - 5.2

x = -12.3

2) -3.4 - x = 2.8

-3.4 - x + 3.4 = 2.8 + 3.4

-x = 6.2

x = -6.2

3) 15.7 + x = 11.35

15.7 + x - 15.7 = 11.35 - 15.7

x = -4.35

4) -8.82 + x = -9.54

-8.82 + x + 8.82 = -9.54 + 8.82

x = -0.72

5) 6.73 - x = -10.58

6.73 - x - 6.73 = -10.58 - 6.73

-x = -17.31

x = 17.31

6) -12.48 - x = -5.28

-12.48 - x + 12.48 = -5.28 + 12.48

-x = 7.2

x = -7.2

7) x - 5.52 = -8.24

x - 5.52 + 5.52 = -8.24 + 5.52

x = -2.72
