Question

Vera and Vikki are sisters. Vera is 4 years old and Vikki is 13 years old. What age will each sister be when Vikki is twice as old as Vera

Answer 1

age of vicky = 13

age of verra = 4

let time = x years

so ,

2(4+x)=13+x

8+2x=13+x

2x-x=13-8

x=5

age of Vicky = 13+5=18

age of verra =4+5=9

hope it helps

Answer 2

13+x = 2(x+4)

 

13 + x = 2x + 8

 

0 = 2x + 8 - 13 - x

 

0 = x - 5

 

x = 5

 

In 5 years Vera will be 9 and Vikki will be 18
