Kim is 9 years older than her siater. kim is one more than 3 times her sisters age. How old is kim?

Answer 1

Let siate age = x

And Kim aged = x + 9

Since kim age is one more than 3 times siate age

Therefore:

x + 9 = 1 + 3x

9 - 1 = 3x - x

8 = 2x

x = 4 (Siate age)

Kim age is 1 more than 3 times Siate age:

1 + 3x = 13 Kim age.
