Question

(8ori8-32-12:k)-(40-2ori10)=3ori3

Answer 1

(8x8-32-12: k) - (40-2x10)=3x3
(64-32-12 : k) - (40-20 )= 9
(32-12 : k)-20=9
32-12 : k=20+9
32-12 : k= 29
12 : k= 32-29
12 : k =3
k = 12: 3
k = 4

Answer 2

(64-32-12:k)-(40-20)=9
(32-12:k)-20=9
(32-12:k)=20+9
32-12:k=29
12:k=29+32
12:k=61
k=61:12
k=...
