Tanya is 1 year less than three times the age of her sister Jessica. Jessica is five years old. How old is Tanya? Need an equation

T = 3J -1

To find Tanya's age, let's first assign variables to the information given in the question.

Let's say:
T = Tanya's age
J = Jessica's age

It is given that Jessica is five years old, so J = 5.

According to the question, Tanya is one year less than three times Jessica's age. Mathematically, this can be represented as:

T = 3J - 1

Substituting the value of J into the equation, we have:

T = 3(5) - 1

Simplifying further:

T = 15 - 1
T = 14

Therefore, Tanya is 14 years old.
