Question

Lindsey is asked about her age. She answers as follows. "My age is 4 years more than three times the age of my son. The sum of our ages is 68 years."

Answer 1

Step-by-step explanation:

let Lindsey age be x,

four more than three time = 3x + 4

let her son age be also x ,

now ,

3x + 4 + x = 68 years

4x + 4 = 68

4x = 68 - 4

4x = 64

x = 64/4

x = 16

means her son's age is 16 .

now her age is 3x + 4 .

so , x = 16

means ,

3 × 16 + 4 = 52

so, Lindsey age = 52

HOPE YOU GOT IT :)
