Question

6+26×10:[5+4(18+20:a×6):24]-22=10

Answer 1

26*10:[5+4(18+20:a*6):24]=10+22-6=26

10:[5+4(18+20:a*6):24=26:26=1

5+4(18+20:a*6):24=1*10=10

4(18+20:a*6):24=10-5=5

4(18+20:a*6)=5*24=120

18+20:a*6=120:4=30

20:a*6=30-18=12

20:a=12:6=2

a=10

Answer 2

6+260:[5+4(18+20:ax6):24]=10+22=32 260:[5+4(18+20:ax6):24]=32-6=26 5+4(18+20:ax6):24=260:26=10 4(18+20:ax6):24=10-5=5 4(18+20:ax6)=5x24=120 18+20:ax6=120:4=30 20:ax6=30-18=12 20:a=12:6=2 a=20:2=10 a=10 se rezolva prin metoda mersului invers, retrograd
