Question

b. A girl is (x)yearsold. Her father is 5 more than 2 times her age. The sum of their ages
is 50 years.
​

Answer 1

Step-by-step explanation:

let age of a girl =x years

age of her father =y years

according to the question,

5+2x=y. (1)

x+y=50

x=50-y (2)

put the second equation in first,

5+2x=y

5+2(50-y)=y

5+100-2y=y

105=y+2y

105=3y

y=105/3=35

x+y=50

x+35=50

x=50-35

x=15

age of a girl=15 years

age of her father =35 years
