Question

solve full question proper​

Answer 1

let the marks be x and y

so x+y = 30.......equation one

now (x+2)×(y-3)......

now solve the equations simultaneously

xy-3x+2y-6....equation 2

therefore,

xy-3x+2y=6

3(x+y=30) = 3x+3y=90

=>. xy+5y=96

taking y common

x+5=96/y

therefore x=(96/y)-5

now by putting value of x in equation one 96/y-5+y=0

now solve it,
