Question

calculează (3×9+9:h)+5×4:2-(12-4×2)=6×6

Answer 1

(3 * 9 + 9 : h) + 5 * 4 : 2 - (12 - 4 * 2) = 6 * 6
(27 + 9 : h) + 10 - (12 - 8) = 36
(27 + 9 : h) + 10 - 4 = 36
(27 + 9 : h) + 6 = 36
27 + 9 : h = 36 - 6
9 : h = 30 - 27
9 : h = 3
9 = 3h
h = 9 : 3
h = 3

Answer 2

(3×9+9:h)+5×4:2-(12-4×2)=6×6
(27+9:h)+10-4=36
(27+9: h) +6=36
27+9:h=36-6
27+9:h=30
9:h=30-27
9:h=3
h=9:3
h=3
