ajutor!!! (2×3+d)-(7×9+6)=7×7 (e-5×6+10×5)-50+4×8=42 (96-3×4-5×8)+f-9×7=13 (23-6×3+g)+3×9-8×3-28=34 (3×9+7×h-53)+5×2-(12-4×2)=6×6 8×8-32-(6×i-51)-(40-2×10)=3×3 VĂ ROG DAU COROANA+100 DE PUNCTE!!! A nu sunt împreună

Answer 1

(6+d)-(63+6)=49
6+d-69 = 49
d = 49+69-6
d = 118-6
d = 112

(e-30+50)-50+32 = 42
(e-30+50)-50 = 42-32
(e-30+50) -50 = 10
e-30+50 = 10+50
e-30+50 = 60
e-30 = 60-50
e-30 = 20
e = 20+30
e = 50

(96-12-40)+f-63 = 13
(84-40)+f = 13+63
44+f = 76
f = 76-44
f = 32

(23-18+g)+27-24-28 = 34
(5+g)+27-24 = 34+28
(5+g)+27-24 = 62
(5+g)+27 = 62+24
(5+g)+27 = 86
5+g = 86-27
5+g = 59
g = 59-5
g = 54


(27+7*h-53)+10-(12-8) = 36
(27+7h-53)+10-4 = 36
(27+7h-53)+10 = 36+4
(27+7h-53) +10 = 40
27+7h-53 = 40-10
27+7h-53 = 30
27+7h = 30+53
27+7h = 83
7h = 83-27
7h = 56
h = 56:7
h = 8

64-32-(6i-51)-(40-20) = 9
32-(6i-51)-20=9
32-(6i-51)=9+20
32-(6i-51) = 29
32-29 = 6i-51
3 = 6i-51
3+51 = 6i
54 = 6i
i = 54:6
i = 9
