Explicación paso a paso:
DESARROLLA LAS ECUACIONES:
1) 21 + x = 26
x = 26 - 21
x = 5
2) 12 + x = 16
x = 16 - 12
x = 4
3) x - 2 = 10
x = 10 + 2
x = 12
4) x + 7 = 12
x = 12 - 7
x = 5
5) x + 15 = 28
x = 28 - 15
x = 13
6) x + 18 = 12
x = 12 - 18
x = -6
7) x - 13 = 24
x = 24 + 13
x = 37
8) x + 14 = -32
x = -32 -14
x = -46
9) x + 2 = 14
x = 14 - 2
x = 12
10) x + 14 = 10
x = 10 - 14
x = -4
11) x + 19 = 21
x = 21 - 19
x = 2
12) x + 24 = 36
x = 36 - 24
x = 12
13) x + 18 = 9
x = 9 - 18
x = -9
14) x - 12 = 12
x = 12 + 12
x = 24
