Answer 2

Answer:

41 years ago

Step-by-step explanation:

Let the no. of years ago be x.

Then, the equation we need would be :

=> 80 - x = 3(54 - x)

=> 80 - x = 162 - 3x

=> 2x = 82

=> x = 41

Sally's mother was 3 times her age 41 years ago

Checking

=> Sally = 54 - 41 = 13

=> Mom = 80 - 41 = 39

=> 13 x 3 = 39 [∴Verified]
