Question

How old am I if 400 reduced by twice my age is 244?

Answer 1

My age is 78 years.

Explanation:

Define my age first as a variable.
Let my age be `x` years.

Reduced by means subtracted.
Subtract twice my age from 400 to get 244:

`400 - 2x = 244`

`400-244 = 2x" "larr` make x positive and isolate it.

`156 = 2x`

`78 =x`
