If x-1/3=k and k=3 what is the value of x?

You said                        x - 1/3 = k

And you also said         k = 3        

So we know that             x - 1/3 = 3

Add  1/3  to each side:    x         =  3-1/3

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
