Question 1168745

Sherry is half as old as her mother. Twelve years ago, she was one third of her mother’s age. Find their ages
now.

CAN YOU ALSO PLEASE USE THE GUESS MEHTOD

THANK YOU
<pre>Let daughter's age be D
Then mother's is: 2D
Three years ago, mother was THREE times daughter's age
We then get: 2D - 12 = 3(D - 12)
2D - 12 = 3D - 36
2D - 3D = - 36 + 12
- D = - 24
Daughter's age, or {{{highlight_green(matrix(1,5, D, "=", (- 24)/(- 1), "=", 24))}}}
You should now be able to find mother's age!!
