Laxmi’s father is 49 years old. He is 4 years older than three times Laxmi’s age. What is Laxmi’s age?

Solution
Let Laxmi’s age be x years.
3 × Laxmi’s age + 4 = Her father’s age
3x + 4 = 49
3x = 49 - 4 ...(Transposing 4 to R.H.S.)
3x = 45
Dividing both sides by 3,
`(3x)/3 = 45/3`
x = 15
Therefore, Laxmi’s age is 15 years.
