    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



    make x positive and isolate it.

    156

    =

    2

    x

    78

    =

    x

    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
