-7yt/3x= ?/18xyt i got 6yt/6yt the answer being 1yt/18xyt

To solve the equation (-7yt/3x) = (?/18xyt), you need to cross-multiply and then simplify.

Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and vice versa.

So, to cross-multiply, you multiply -7yt with 18xyt, and 3x with ?:

(-7yt) * (18xyt) = (3x) * (?)

Simplifying this equation gives you:

-126xy^2t^2 = 3x * ?

To continue solving, we need the value of the right-hand side, which you provided as 6yt/6yt. However, this expression doesn't help us determine the value of ?.

If you have the value of ? or a related equation, please provide it so that I can assist you further.
