Răspuns:

34 - 80 : {[(24 : a - 2) × 7 + 6} = 26

80 : {[(24 : a - 2) × 7 + 6} = 34 - 26

80 : {[(24 : a - 2) × 7 + 6} = 8

[(24 : a - 2) × 7 + 6 = 80 : 8

[(24 : a - 2) × 7 + 6 = 10

[(24 : a - 2) × 7  = 10 - 6

[(24 : a - 2) × 7 = 4

24 : a - 2 = 4/7

24 : a = 4/7 + 2

24 : a = 18/7

a = 24 : 18/7

a = 24 x 7/18

a = 4x7/3

a = 28/3
