Answer 2

Răspuns:

Explicație pas cu pas:

a/7 = 2/(b+1)  <=> a(b+1) = 14  =>

a = 1 ; b+1 = 14 => b = 13

a = 2 ; b+1 = 7 => b = 6

a = 7 ; b+1 = 2 => b = 1

a = 14 ; b +1 = 1 => b = 0

a = -1 ; b+1 = -14 => b = -15

a = -2 ; b+1 = -7 => b = -8

a = -7 ; b+1 = -2 => b = -3

a = -14 ; b+1 = -1 => b = -2
