Question

Jane's cousin Maggie is 3 times as old as Jane.

After 4 years, the cousin will be 2 times as old as Jane.

Let x= Jane's age

Jane's age today =

Maggie's age today=  

Answer 1

Jane is 4 years old

Maggie is 12 years old

in 4 years, they'll be 8 and 16

16 = 2 times 8

let x = Janes's age now, and y = Maggie's age now

y =3x

y+4 = 2x + 8

3x +4 = 2x + 8

3x-2x = 8-4 = 4

x = 4 = Jane's age

y = 3(4) = 12 = Maggie's age
