b+d=15

a+c=19

________

a+b+c+d = 34

Step-by-step explanation: Since 30 ≠ 34 , the values does not exist .

[Hint and Clue : If you get these types of questions , try to add or subtract or factorize any 2 pair of equations and then do the same proceedure for next 2 pairs . If you find any contradiction , just conclude its not possible . Dont break your head and waste time for wrong questions ....  Keep Going !!! ]
