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.
