If x-1/3=k and k=3 what is the value of x sat math section 3

First, start with plugging K's value in:

x-1/3 = k
x-1/3 = 3

Then solve to get the x alone:

x-1/3 *3 = 3 *3
x-1 = 9
x-1 +1 = 9+1
x = 10

(& because I'm not entirely sure about what the equation saysi'll solve the another way)

x-1/3 = 3
x-1/3 +1/3 = 3 +1/3
x = 3 1/3

He secknd step was the answer to them
