How old am I if 400 reduced by 2 times my age is 244? How do you solve it and what is the answer?

Answer: My age is 78 years.

Step-by-step 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 <- - make x positive and isolate it

156/2 = 2x/2 <- - 2x cancels out and becomes just x

78 = x
