V or x is something so if you add 9 to get 8 then you must subtract 9 from 8 to get -1 which would be your answer
x=-y/3 +9 i believe that should help you
64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
