,,Alfabet...matematic: ..(9×9-6×6-a)+(13+28:4)=5×10+3; b): (99-b-3×8)+2×6:2=8×2+5×10;..c)..(6×4:3+c):7=16:4; d)..(9×4:6×d)-5×5=45:9; e)..(e-5×6+10×5):5+4×8=42; f)..(96-3×4-5×8)+f-9×7=13; g)..(23-6×3+g)+3×9-8×3:6=34; h)..(3×9+9:h)+5×4:2-(12-4×2)=6×6;..va rog sa ma ajutati..

Answer 1

a)(81-36-a)+13+7=53
(81-36-a)+13=53-7
81-36-a=46-13
45-a=33
a=45-33
a=12
b)(99-b-24)+6=16+50
99-b-24=66-6
99-b=60+24
b=99-84
b=15
c)(8+c):7=4
8+c=7×4
c=28-8
c=20
d)(6×d)-25=5
6d=25+5
d=30:6
d=5
e)(e-30+50):5+32=42
(e-30+50):5=42-32
(e-30+50)=10×5
e-30=50-50
e=30
f)(96-12-40)+f-63=13
(84-40)+f=63+13
44+f=76
f=76-44
f=32
g)(23-18+g)+27-4=34
(5+g)+27=34+4
5+g=38-27
g=11-5
g=6
h)(27+9:h)+10-4=36
(27+9:h)+10=36+4
27+9:h=40-10
9:h=30-27
h=9:3
h=3
