Donna is 14 years older than her cousin, Cash. She is also 3 times as old as Cash. Let X represent Cash's current age and write an equation to solve for their ages.

Question

Mostly looking for Donna's age/

Answer 1

Call x cash's age and y Donna's age.

is means =

Donna is: y =

14 years older means add 14.

Donna is 14 years older than Cash: y = x + 14

Three times as old as means multiply by 3: y = 3x.

you can set the equations equal to each other to solve for x, Cash's age: x + 14 = 3x

14 = 2x

7 = x = Cash's age,

y = 3x = 3*7 = 21, which is Donna's age.
