Explicație pas cu pas:
50-5x{35-[5x(40-36:ax8:2):8-7]-9}:2+5=10
50-5x{35-[5x(40-36:ax8:2):8-7]-9}:2 = 10-5
50-5x{35-[5x(40-36:ax8:2):8-7]-9}:2 = 5
5x{35-[5x(40-36:ax8:2):8-7]-9}:2 = 50 - 5
5x{35-[5x(40-36:ax8:2):8-7]-9}:2 = 45
5x{35-[5x(40-36:ax8:2):8-7]-9} = 45×2
5x{35-[5x(40-36:ax8:2):8-7]-9} = 90
35-[5x(40-36:ax8:2):8-7]-9 = 90 : 5
35-[5x(40-36:ax8:2):8-7]-9 = 18
35-[5x(40-36:ax8:2):8-7] = 18+9
35-[5x(40-36:ax8:2):8-7] = 27
5x(40-36:ax8:2):8-7 = 35 - 27
5x(40-36:ax8:2):8-7 = 8
5x(40-36:ax8:2):8 = 8+7
5x(40-36:ax8:2):8 = 15
5x(40-36:ax8:2) = 15×8
5x(40-36:ax8:2) = 120
40-36:ax8:2 = 120 : 5
40-36:ax8:2 = 24
36 : a x 8 : 2 = 40 - 24
36 : a x 8 : 2 = 16
36 : a = 16 × 2 : 8 → aplic metoda mersului invers
36 : a = 32 : 8
36 : a = 4
a = 36 : 4
a = 9
