Solucion

21x = 21 - 2x + 3

21x + 2x = 21 + 3

23x = 24

x = 24 / 23 = 1, 043

13x + 3 = 169

13x = 169 - 3

13x = 166

x = 166 / 13

x = 12, 76

100x + 2 = 10

100x = 10 - 2

100x = 8

x = 8 / 100

x = 0, 08

8x + 1 = 64( - x + 3)

8x + 1 = - 64x + 192

8x + 64x = 192 - 1

72x = 191

x = 191 / 72

x = 2, 65

2 5 - x = 1 - x = 1 - 25 - x = - 24

x = 24

saludos.
