Question

If x-1/3 = kand k = 3, what is the value of x?
a. 2
b. 4
c. 9
d. 10

Answer 1

x-1/3 = k

or, x-1/3 = 3 ( putting k = 3 )

or, x-1/3+1/3 = 3+1/3 ( adding 1/3 to both sides of the equation)

or, x = 3+1/3

or, x = {3(3)+1}/3

or, x = 10/3

Hopefully it helped you.

Answer 2

X=10

Explanation:

Plug 3 into the k in the first equation. Multiply by 3 to cancel out the fraction. This leaves you with x-1=9. Add 1 to both sides and you get x=10.
