Question

a + b = 300
b=cx 9
c= d + 13
d=e: 6
e: 6 = 19​

Answer 1

a + b = 300

Prima data aflam e :

e : 6 = 19

e = 19 × 6

e = 144

Acum aflam d :

d = e : 6 =

d = 144 : 6

d = 19

Acum aflam c :

c = d + 13

c = 19 + 13

c = 32

Acum aflam b

b = c × X × 9

b = 32 × 9 × X

b = 288 + X ( la b nu se intelg ce ai vrut sa zici )
