Answer:

32

Step-by-step explanation:

You dont know my age, let's call it x

Four times my age is then 4x.

"Reduced by" means subtraction.

200 reduced by...

means 200 -

200 - 4x = 72

Subtract 200 from both sides.

-4x = 72 - 200

-4x = -128

Divide both sides by -4.

x = 32

The unknown age is 32.
