Verified answer

1) х + 9 = 3
х=-6
2) 5 – х = -7
х=12
3) 8 – х = -2
х=10
4) х - (-5) = -8
х=-13
5) –х - (-1) = -9
х=10
6) -х - (-7) = 2
х=5

Tiruhi 1) х + 9 = 3
x=3-9
x=-6

2) 5 – х = -7
x=5-(-7)
x=5+7
x=12

3) 8 – х = -2
x=8-(-2)
x=8+2
x=10

4) х - (-5) = -8
x=-8-5
x=-13

5) –х - (-1) = -9
-x=-9-1
-x=-10
x=10

6) -х - (-7) = 2
-x=2-7
-x=-5
x=5
