Question 661082: Cara is three times as old as Madeline. In 10 years she will only be twice Madeline's age. How old was Cara 4 years ago?



3x=2x+10
x=10
3x=30
Cara's age for years ago would be 26.


or 2x=10
x=5
3x=15
15-4=11 years old as Cara's age (4 years ago.)

Hi,

madeline: x NOW

Cara:  3x  NOW

Question states*** in ten years ....

Assuming Your Original Work Up was...

+3x+%2B+10+=+2%28x%2B10%29****

 3x + 10 = 2x + 20

     x = 10, Madeline's age  and Cara's age is 30.

Cara is three times as old as Madeline. In 10 years she will only be twice Madeline's age. How old was Cara 4 years ago?
========================================
C = 3M
C+10 = 2(M+10) = 2M+20
3M+10 = 2M+20
M = 10
---------
C = 30
C-4 = 26
