casey is six time as old as Ralph, In two years, she will be four time as old as Ralph. How old is each of them now?
Keith_Richards [23]

Casey is 18 years old and Ralph is 3 years old.

Step-by-step explanation:

Let,

Age of Casey = x

Age of Ralph = y

According to given statement;

x = 6y     Eqn 1

In two years

x+2=4(y+2)

x+2=4y+8

x = 4y+8-2

x = 4y+6     Eqn 2

Putting value of x from Eqn 1 in Eqn 2

6y=4y+6 \\6y-4y=6\\2y=6

Dividing both sides by 2

\frac{2y}{2}=\frac{6}{2}\\y=3

Putting y=3 in Eqn 1

x=6(3)\\x=18

Casey is 18 years old and Ralph is 3 years old.
