$\huge\boxed{\fcolorbox{cyan}{Red}{Solution:-}}$.

➡Given here,

↪let, Age of X = P.

↪Age of y = q.

➡A/c to questions .

↪p+q = 50..........(1)

And,

↪p:q= 7:3.

↪p/q = 7/3.

↪3p-7q= 0...........(2)

[ equations 3×(1) - (2).

↪3p+3q= 150........(3)

↪3p-7q= 0.............(4).

-

↪10q= 150.

↪q= 15.

[ by (1). ]

↪p= 50-15.

↪p= 35.

➡Thus:-

♠Age of x =35years .

♠Age of y= 15years.
