Resuelve las siguientes ecuaciones con números enteros:

a) 5(3 + x) = 10


b) x : 3 + 1 = 16


c) – 3 + 2 (x – 1) = 5


d) – 2 + (- 3) = 4 + 3 (x – 2)


e) 2x + 5x – 10 = 3x – 6


f) – 3 (2x + 7) = 1 – 4x


g) 3 (x – 2) = 4x + 1


h) – 2 (4x + 5) = - 5x + 14


i) 3(3x + 2) = 2 (8 + 2x)


j) (3x + 1)2 = 49


k) 3 (x2 – 2) + 3 = 45
