Explicație pas cu pas:
[(3 + a : 2) : 11 + 7] × 5 - 9 = 41
[(3 + a : 2) : 11 + 7] × 5 = 41+9
[(3 + a : 2) : 11 + 7] × 5 = 50
(3 + a : 2) : 11 + 7 = 50 : 5
(3 + a : 2) : 11 + 7 = 10
(3 + a : 2) : 11 = 10 - 7
(3 + a : 2) : 11 = 3
3 + a : 2 = 3 × 11
3 + a : 2 = 33
a : 2 = 33 - 3
a : 2 = 30
a = 30 : 2
a = 15
____________________
[(b + 5) : 4 - 4] × 8 + 6 = 14
[(b + 5) : 4 - 4] × 8 = 14 - 6
[(b + 5) : 4 - 4] × 8 = 8
(b + 5) : 4 - 4 = 8 : 8
(b + 5) : 4 - 4 = 1
(b + 5) : 4 = 1 + 4
b + 5 = 5 × 4
b = 20 - 5
b = 15
_______________
a = b = 15
a + b = 15 + 15 = 30 → suma
a - b = 15 - 15 = 0 → diferența
a × b = 15 × 15 = 225 → produsul
a : b = 15 : 15 = 1 → câtul
