Answer 1

Step-by-step explanation:

let ages of both are x and y respectively

then by all statement We get

x + y = 20

y = (20 - x) .....(i)

and

( x - 4 )( y - 4 ) = 48 .......(ii)

put value of y in equation (ii) from equation (i)

( x - 4 )(20 - x - 4 ) = 48

$(x - 4)(16 - x) = 48$

$16x - {x}^{2} - 64 + 4x = 48$

${x}^{2} - 20x + 112 = 0$

this equation is not soluble

and value of x is imaginary

which is not possible

Therefore this satuation is not possible
