Question

A wise man once said, "400 reduced by 3 times my age is 163." Write and solve a two-step equation to determine his age.

Answer 1

hey

Explanation:

let the age of man be x

400-3x=163

400-163=3x

237/3=x

x= 79

Answer 2

Explanation:

Let x be the age of wise man

3 time his age = 3x

400 reduced by 3 times his age = 400 - 3x

400 - 3x = 163

-3x = 163 - 400

-3x = -237

x = -237/-3

x = 79 years
