%28-7yt%29%2F%283x%29=+Z+%2F%2818xt%29+
Treat this like solving a ratio
%28-7yt%29%2F%283x%29=+Z%2F%2818xt%29+
%2818xt%29%2A%28-7yt%29%2F%283x%29+=+Z+
-126xyt%5E2%2F3x+=+Z+
-42yt%5E2+=+Z+
So the answer is
%28-7yt%29%2F%283x%29=+%28-42yt%5E2%29%2F%2818xt%29+

-7yt/3x=?/18xyt
3x?=-7yt*18xyt
3x?=-126xy^2t^2
?=-126xy^2t^2/3x
?=-42y^2t^2 answer.
Proof:
-7yt/3x=-42y^2t^2/18xyt
3x(-42y^2t^2=-7yt(18xyt)
-126xy^2t^2=-126xy^2t^2
