hey..
let the age of father be x and son be y
x + y = 56 ..... (1)
x - y = 54 ....... (2)
(1) + (2)
x + y + x - y = 56 + 54
2x = 110
x = 110/2
x = 55
sub x in (1)
x + y = 56
55 + y = 56
y = 56 - 55
y = 1
therefore the age of father is 55 years and son is 1 year

suppose
age of father is x &
age of his son is y
first condition
x+y=56
second condition
x-y = 54
add both equation
2x=110
x=55
y=1
