What you placed inside the rendering tags does not properly nor completely display:
z varies jointly as the square root of the product of x and y. Ij z=3 when x=3 and y=12, find x when z=6 and y=64 .

What is the "Ij"?

The description makes for this:
z=k%2Asqrt%28xy%29, the first sentence.
k is a variation constant.

The two parts of the second sentence are these.
system%28x=3%2Cy=12%2Cz=3%2Ck=unknownCanBeFound%29
-
system%28x=solveForThisNow%2Cy=64%2Cz=6%2Ck=NowKnown%29
-
Solve first for k and evaluate.
Next, solve for x and evaluate.
