"x varies directly as the square of y and inversely as z" translates to (let me know if you need help with the translation)

Start with the given equation.

Plug in y=6, z=3 and x=112

Multiply both sides by 3.

Multiply

Square 6 to get 36

Divide both sides by 36 to isolate 'k'.

Reduce

So the constant is

-------------------------------

So the equation is:

Plug in , y=3 and z=3

Square 3 to get 9

Multiply and reduce
