Answer 1

Answer:

let the marks secured by Anuradha be X

let the marks secured by radhika be X+8

according to the question,

The sum of their marks:

X+(X+8)=76

X+X+8=76

2X=68

X=34

therefore,marks of Anuradha is 34 and marks of radhika is (34+8) 48

Radhika's marks= x

Anuradha's marks= y

The pair of equations according to question:

• x+y=76
