$(-2u^3v + 5uv - 1) +(7u^3v - 2u^2v^2) +(5u^2v^2 - uv + 6)=\\\\ -2u^3v + 5uv - 1 +7u^3v - 2u^2v^2 +5u^2v^2 - uv + 6= \\ \\ (7u^3v-2u^3v)+(5u^2v^2-2u^2v^2)+(5uv-uv)+(6-1)=\\\\ \boxed{5u^3v+3u^2v^2+4uv+5}$

Eya is 5 years younger than 3 times Bills age. If Eya is 28 how old is Bill?

Sedaia [141]

Bill's age = x

Eya's age = 3x - 5

Eya is 28

28 = 3x - 5

28 (+5) = 3x -5 (+5)

33 = 3x

33/3 = 3x/3

x = 11

Bill = x

x = 11

Bill is 11 years old
