A man is 30 years older;this means that the man is 30 years more than his daughter and the daughter's age is unknown which makes the man's age to b(30+x) while the daughter remains as x and the sum of their ages is 48 which means that (30+x)+x=48
By opening the bracket:
30+x+x=48
30+2x=48
2x=48-30
2x=18
X=18/2
X=9
This means that the daughter's age is 9years

The correct answer is B) 9 years.
Let the man's age be M and let the daughter's age be D.
The man is 30 years older than his daughter: M = D + 30
The sum of their ages is 48: M + D = 48
Joining the equations:
D + 30 + D = 48
2D = 48 - 30
2D = 18
D = 9.
