To calculate for age, let x be the years of his age. The problem can be equated as 400 -4x =116.
To solve for x, subtract both sides by 116.
> 400 -4x -116=116-116
> 284-4x =0
Add both sides by 4x
> 284-4x+4x =0+4x
> 284=4x
Divide both sides by 4 to get the value of x.
> 284/4=4x/4
> 71=x
The value of x is 71 and since x represent years of age, then the age is 71 years old.
