Question

repede va rog e urgent dau coroana și dau si 20 de puncte ​

Answer 1

a×2=b
b÷2=a
b÷3=c
c×3=b
c+36=d
d-36=c
d-19=83
83+19=d
d=102
102-36=c
c=66
66×3=b
b=198
198÷2=a
a=99

a-304=b
b+29=c
c÷4=d
d×6=294
b+304=a
c-29=b
d×4=c
d=294÷6
d=49
c=49×4
c=196
196-29=b
b=167
167+304=a
a=471

a+b=300
b=c×9
c=d+13
d=e÷6
e÷6=19
e=19×6
e=114
d=114÷6
d=19
b=32×9=288
a+288=300
a=300-288
a=12

a×b=90
b=c×3
c=d÷10
d-e=250
e÷10=5
e=10×5=50
d-50=250=50+250=300
c=300÷10=30
b=30×3=90
a×90=90
a=90÷90=1
Succes!
