Question

(3×9+9:h)+5×4:2-(12-4×2)=6×6

Answer 1

(3x9+9:h)+5x4:2-(12-4x2)=36
(27+9:h)+10-4=36
27+9:h+10=36+4=40
27+9:h=40-10=30
9:h=30-27=3
h=3x9=27
h=27

Answer 2

(27+9/h)+10-(12-8)=36

/27h+9/h +10-4=36

/27h+9/h +6=36, h≠0.

/27h+9/h =36-6

/27h+9/h =30

27h+9=30h

27h-30h=-9

-3h=-9

h=3, h≠0.

h=3.
