A wise man once said, "400 reduced by 3 times my age is 208" What is the mans age

96

Step-by-step

explanation:

400−2x=208. 400−208=2x. 192=2x. x=96

The wise man is 64 years old

Step-by-step explanation:

"400 reduced by 3 times my age is 208"

we don't know the man's age, so we can substitute it for x. This means 400-3x=208. Using this equation, we can now solve for x to find the man's age.

400-3x=208

400-208=3x

192=3x

64=x

Checking

400-3•64=

400-192=208
