Hello!

Answer:


\Large \boxed{\sf 76}

Explanation:

→ Let my age be x.

→ We have this equation:


\sf 300 - 3x = 72

→ Let's solve x in this equation to find my age:

Subtract 300 from both sides:


\sf 300 - 3x -300= 72-300

Simplify both sides:


\sf - 3x = -228

Divide both sides by -3:


\sf (-3x)/(-3) = (-228)/(-3)

Simplify both sides:


\boxed{\sf x = 76}

Conclusion:

If 300 reduced by 3 times my age is equal to 72, my age is 76.
