Question

give the answer of this question ​

Answer 1

Step-by-step explanation:

Let fill a in first box

b in second one and c in third one thus by logic we have to fill a in fourth box thus equations we get are

a+b = 8

a+c = 13

c-a=6

subtract third eqn from second

2a = 7

a = 3.5

b = 4.5

c = 9.5
