Question

determinati-l pe x din : 6 x 2 + {24 : 6 + [3 x 8 + (x:4 + 4) : 2] - 3 x 8 } = 33 ....... URGENT !!!! 20 puncte + coroana !!!

Answer 1

6 x 2 + {24 : 6 + [3 x 8 + (x:4 + 4) : 2] - 3 x 8 } = 33
12 + {4 + [24 + (x:4 + 4) : 2] - 24 } = 33
4 + [24 + (x:4 + 4) : 2] - 24 = 33 - 12
4 + [24 + (x:4 + 4) : 2] - 24 = 21
4 + [24 + (x:4 + 4) : 2] = 21 + 24
4 + [24 + (x:4 + 4) : 2] = 45
24 + (x:4 + 4) : 2 = 45 - 4
24 + (x:4 + 4) : 2 = 41
(x:4 + 4) : 2 = 41 - 24
(x:4 + 4) : 2 = 17
x:4 + 4 = 17 × 2
x:4 + 4 = 34
x:4 = 34 - 4
x:4 = 30
x = 30 × 4
x = 120
