ases
(b) A man's age is 30 years more than the age of his son. If the sum of their ages is
56 years, find the age of the son
.​

Answer 1

Step-by-step explanation:

ANSWER

Let the age of son be x and that of his father be y.

According to the question

y=x+30−(i)⟹y−x=30

and x+y=56−(ii)

Solving equations (i) and (ii)

y=43

x=56−43=13

∴ son's age=13years.

Answer 2

Step-by-step explanation:

let the age of the son be x

then the age of the father will be 30+x

according to question,

x+30+x=56

2x+30=56

2x=56-30

2x=26

x=26÷2

x=13

therefore the age of the son is 13 years
