PLZ HURRY carrie is 3 times as old as Eva. in 15 years Carrie will be twice as old as Eva. how old are they both now

Carrie is 45 years old and eva is 15 years old

If carrie is 3 times as old as Eva, then;

x = 3y

If in 15 years Carrie will be twice as old as Eva, then;

(x+15) = 2(y+15)

Substitute equation 1 into 2

3y + 15 = 2y + 30

y = 30 - 15

y = 15

Since x = 3y

x = 3(15)

x = 45

Hence Carrie is 45 years old and eva is 15 years old

Age of Eva =  15 Years

Age of Carrie = 45 Years

Step-by-step explanation:

Let the age of Eva be X years

Given that Carrie is 3 times as old as Eva

Therefore age of Carrie = 3X YEARS.

After 15 years

Age of Eva = X + 15

Age of Carrie = 3X +15

Given that Carrie is twice as old as Eva

so according to this condition

age of Carrie = 2*Age of Eva

Substituting the age of Eva and Carrie

3X +15 = 2*(X + 15 )

=> 3X +15 = 2X +30

=> 3X - 2X = 30 - 15

=> X = 15

Since X was assumed age of Eva so age of Eva is 15 years

age of Carrie = 3X years = 3*15 = 45 years.
