Answer:


(11)/(6)

Explanation:

The equation to be solve is

4x−1/3=7/1

We can go about this by first adding 1/3 to both sides.


4x - (1)/(3) + (1)/(3) = (7)/(1) + (1)/(3)


\implies \ 4x = (7)/(1) + (1)/(3)

We then simplify the the right hand side of the equation


\implies 4x = (21 + 1)/(3)


\implies 4x = (22)/(3)

To find x, we multiply through by 1/4


\implies (1)/(4) * 4x = (22)/(3) * (1)/(4)


\implies x = (22)/(12)


\implies x = (11)/(6)

Hence the solution set in the simplest form for the expression is

{x=11/2}
