Respuesta :
First you had to rewrite the problem with eighteen as the three times six is equal to eighteen.
[tex]=6y-3*6h[/tex]
Then you factor it out by the common term of six.
[tex]=6(y-3h)[/tex]
Final answer: [tex]\boxed{6(y-3h)}[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
