Question

determina valoarea fiecarei litere stiind ca :
a+b=300
b=cx9
c=d+13
d=e:6
e:6=19






a x b=90
b=c x 3
c = d : 10
d-e=250
e :10 = 5

Answer 1

1)
e:6=19
e=19x6
e=114

d=114:6
d= 19

c= 19+13
c=32

b=32x9
b= 288

a+288=300
a=300-288
a=12

2)

e:10=5
e=5x10
e=50

d-50=250
d=250+50
d=300

c=300:10
c=30

b=30x3
b=90

axb=90
ax90=90
a=90:90
a=1




Coronița ????????????????

Answer 2

e:6=19

e=19*6

e=114

d=114:6

d=19

c=19+13

c=32

b=32*9

b=288

a+288=300

a=300-288

a=12

--------------------------------

e:10=5

e=10*5

e=50

d-50=250

d=250+50

d=300

c=300:10

c=30

b=30*3

b=90

a*90=90

a=1............
