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

Nov 18, 2016

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:

$400 - 2 x = 244$

$400 - 244 = 2 x \text{ } \leftarrow$ make x positive and isolate it.

$156 = 2 x$

$78 = x$
