A) 2(b + 1) = 4(b + 2)

2b + 2 = 4b + 8

2b + 4b = 8 - 2 - 2b = 6 - b = 6 / 2 - b = 3

b = - 3

b) 4 - (1 - 2c) = - 6 + (3c + 5)

4 - 1 + 2c = - 6 + 3c + 5

3 + 2c = - 1 + 3c

2c - 3c = - 1 - 3 - c = - 4

c = 4

c) 3(d - 4) + 1 = 2(d - 6) + 4

3d - 12 + 1 = 2d - 12 + 4

3d - 11 = 2d - 8

3d - 2d = - 8 + 11

d = 3

e) 5(f + 3) = - 3 - ( - 2 - 7f)

5f + 15 = - 3 + 2 + 7f

5f - 7f = - 1 - 15 - 2f = - 16

f = - 16 / - 2

f = 8

d) e(e - 2) + 3 = 24 - e(5 - e)

e (cuadrado) - 2e + 3 = 24 - 5e - e (cuadrado)

2e (cuadrado) + 3e - 21 = 0

(tenes que hacer la cuadratica, esta te la debo disculpa).
