I will guess that the original equation is as follows:

. . . . .

...and that the instructions were something along the lines of "Find the expression which makes the two fractions similar." If so, then:

Find the value by which 3x was multiplied, in order to get 18xyt, and multiply -7yt by the same value. :wink:

What did you get when you divided 18xyt by 3x, to find what 3x had been multiplied by to get 18xty?

What did you get when you multiplied -7yt by this same value?

Please show your steps. Once we can see what you did, we'll have a better change to help you find where you may have gone wrong.

Thank you! :D
