Question

5. Determină valoarea fiecărei litere, știind că:​

Answer 1

d - 19 = 87
d= 87 + 19
d = 106

c+36=d
c+36=106
c= 106 - 36
c= 70

b:3=c
b:3=70
b= 70x3
b=210

ax2=b
ax2=210
a=210:2
a= 105
—————————

dx6=294
d=294:6
d=49

c:4=d
c:4=49
c=49x4
c=196

b+29=c
b+29=196
b= 196-29
b=167

a-304=b
a-304=167
a=167+304
a=471
—————————————-

e:6=19
e=19x6
e=114

d=e:6
d=114:6
d=19

c=d+13
c=19+13
c=32

b=cx9
b= 32 x 9
b= 288

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

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

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

c=d:10
c=300:10
c=30

b=c x3
b= 30x3
b=90

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