Casey is six times as old as Ralph. In two years, she will be four times as old as Ralph. How old is each of them now?
lisov135 [29]

Ralph is 3 years old

Casey is 18 years old

Step-by-step explanation:

Equate the two equations for Casey as

6x+2 = 4x+8

6x-4x=8-2

2x=6

x=6/2= 3

Current age;

Ralph= x= 3 years old
