Actually this question is related to Chapter - Linear equations in One Variable. HOPE THIS MAY HELP YOU.
As per your question,
Let the present age of Sahil be 5x
& Present Age of Anwar be 7x
Now,
After 4 years age of Sahil = 5x+4 ------(1)
Similarly,
After 4 years age of Anwar = 7x+4 ------(2)
From equation (1)&(2),
=> 5x+4+7x+4 = 56
=> 5x+7x+4+4 = 56
=> 12x + 8 = 56
=> 12x = 56-8
=> 12x = 48
=> X=48/12=4
Hence,
Present age of Sahil = 5x = 20 years
&
Present Age of Anwar = 7x = 28 years
