Sameer's father is two years more than three times Sameer's age. Write Sameer father's age if Sameer is x years old at present

3x+2

Step-by-step explanation:

Let Sameer age be x years old at present

Three times Sameer's age = 3 * x = 3x

Two years more than three times Sameer's age = 3x + 2

If Sameer's father is two years more than three times Sameer's age, the the age of Sameer's father at present will be (3x+2) years
