Question

75:{5x6-[6x4:(20-12:nx3)-2]:2}+7=10

Answer 1

75:{5•6-[6•4:(20-12:n•3)-2]:2}+7=10 ( facem 10-7)

75:{5•6-[6•4:(20-12:n•3)-2]:2}=3 ( facem 75:3)

5•6-[6•4:(20-12:n•3)-2]:2=25 ( facem 5•6, 6•4)

30-[24:(20-12:n•3)-2]:2=25 ( facem 30-25)

[24:(20-12:n•3)-2]:2=5 ( facem 2•5)

24:(20-12:n•3)-2=10 ( facem 10+2)

24:(20-12:n•3)=12 ( facem 24:12)

20-12:n•3=2 ( facem 20-2)

12:n•3=18 ( facem 18:3)

12:n=6 ( facem 12:6)

n=2
