Cary is 9 years older than dan in 10 years the sum of their ages will be 81 find the age of each now

Alright, lets get started.

Suppose Cary's current age = x

Suppose Dan's current age = y

Cary is 9 years older than Dan (given in question), means :

...............................equation (1)

After 10 years Cary's age = (x+10)

After 10 years Dan's age = (y+10)

In 10 years the sum of their ages will be 81, means

Subtrating 20 in both sides

.................................... equation (2)

From equation (1), putting the value of x in equation (2)

Subtrating 9 in both sides

Dividing by 2 in both sides

It means Cary's age is 35 and Dan's age is 26. : Answer
