Explicație pas cu pas:9*6-16:{[4*9-6*4:(a-2*10)]:5+2}=26*2

54-16:{[36-24:(a-20)]:5+2}=52

54-52 =16:{[36-24:(a-20)]:5+2}

2=16:{[36-24:(a-20)]:5+2}

2*{[36-24:(a-20)]:5+2}=16

[36-24:(a-20)]:5+2=8

[36-24:(a-20)]:5=8-2

[36-24:(a-20)]:5=6

36-24:(a-20)=6*5

36-24:(a-20)=30

36-30 = 24: (a-20)

6=24:(a-20)

6*(a-20)=24

a-20=24:6

a-20=4

a=4+20

a=24

SPOR!
