Ajutatima pls ca habar nu am

Answer 1

10 x + y+ 10z+ v= 45 
10(x+y) + z+v = 45 
x,y≠0 si x≠y
y+ v= 5 
 10+35=45 ⇒xy barat = 10 , zv barat = 35
 30+15=45⇒xy barat = 30 , zv barat = 15

15+30=45 ⇒xy= 15, zv= 30
 35+10=45⇒xy= 35,zv=10

16+29= 45⇒ xy barat = 16 , zv barat = 29
26+19 =45⇒xy barat = 26 , zv barat = 19

 17+28=45 ⇒xy barat = 17 , zv barat = 28
 27+18=45⇒xy barat = 27 , zv barat = 18

18+27=45⇒ xy barat = 18 , zv barat = 27
 28+17=45⇒xy barat = 28 , zv barat = 17

19+26=45 ⇒xy barat = 19 , zv barat = 26
 29+16=45⇒xy barat = 29 , zv barat = 16
