Explanation:
_________________________________________________________

Let "x" represent the numerical value of [the man's age].

500 - 3x = 200 ; Solve for "x" ;

Subtract "500" from each side of the equation:

500 - 3x - 500 = 200 - 500 ;

to get:

- 3x = -300 ;

Now, divide each side of the equation by "-3" ; to isolate "x" on one side of the equation; & to solve for "x" ;

- 3x / -3 = -300 / -3 ;

x = 100 .
