[(2 × n - 10 ) × 6 + 5] : 8 = 22
(2 × n - 10 ) × 6 + 5 = 22 × 8
(2 × n - 10 ) × 6 + 5 = 176
(2 × n - 10 ) × 6 = 176 - 5
(2 × n - 10 ) × 6 = 171
2 × n - 10 = 171 : 6
2 × n - 10 = 28,5
2 × n = 28,5 + 10
2 × n = 38,5
n = 38,5 : 2
n = 19,25
(2 × n - 10 ) × 6 + 5 = 22 × 8
(2 × n - 10 ) × 6 + 5 = 176
(2 × n - 10 ) × 6 = 176 - 5
(2 × n - 10 ) × 6 = 171
2 × n - 10 = 171 : 6
2 × n - 10 = 28,5
2 × n = 28,5 + 10
2 × n = 38,5
n = 38,5 : 2
n = 19,25
