Question

Mike is six less than three times his daughter's age. Mike is 36; how old is his daughter?

Answer 1

Let his daughter's age be x.
Mike's age = 3x - 6
3x - 6 = 36
3x = 36 + 6
= 42
x = 42/3 = 14
Mike's age = 3x - 6
= 42 - 6
= 36

Answer 2

Let mike's daughter's age. then
three times of her age=3x
A/q,
3x-6=36
3x=36+6
3x=42
x=42/3=14

Answer 3

hence,
daughter's age=>x =14
