Respuesta:
1.- x = 8 2.- x = 12 3.- x = 28 4.- x = -3 5.-x = 21
6.-x = -10 7.-x = 5 8.-x = -17 9.-x = -9 10.-x = -16
11.-z = -8 12.-x = 4 13.-x = -5 14.-x = 7 15.-y = -6
16.-x = 0 17.-x = 7 18.-x = 34 19.-v = 44 20.-x= 28
21.-x = 40 22.- z = 13
Explicación paso a paso:
1) x + 3 = 11
x = 11 - 3
x = 8
2)x - 5 = 7
x = 7 + 5
x = 12
3)x - 8 = 20
x = 20 + 8
x = 28
4)x + 2 = -1
x = -1 - 2
x = -3
5)x - 9 = 12
x = 12 + 9
x = 21
6)x + -3 = -7
x = -7 - -3
x = -10
7)x - 8 = -3
x = -3 + 8
x = 5
8)8 + x = -9
x = -9 - 8
x = -17
9)-12 + x = 3
x = 3 - -12
x = -9
10)-7 - x = -9
x = -9 + -7
x = -16
11)-5 + z = -3
z = -3 - -5
z = -8
12)-2 + x = -4 + 6
-2 + x = 2
x = 2 - -2
x = 4
13)3 + x - 2 = -4
x + 1 = -4
x = -4 - 1
x = -5
14)15 - x - 5 = 3 - 7 - 1
x - 10 = 3
x = 3 - 10
x = 7
15)2 + y = -3 - 1
2 + y = -4
y = -4 - 2
y = -6
16)7 + x - 7 = 5 - 4 - 1
x = 0
17)x - 7 = 0
x = 0 + 7
x = 7
18)3 - x = 7 + 24
3 - x = 31
x = 31 + 3
x = 34
19)40 - 1 = 2 - v + 3
39 = 5 - v
39 + 5 = v
v = 44
20)4 - x - 8 = 30 - 6
x - 4 = 24
x = 24 + 4
x= 28
21)4 - x - 2 = 30 + 8
x - 2 = 38
x = 38 + 2
x = 40
22)2 + z - 1 = 7 + 7
z + 1 = 14
z = 14 - 1
z = 13
espero te sirva mucho
