Answer 1

@Qwertty123. @Qwertty123 so you would add -9?

Answer 2

yes. :)

Answer 3

yes.
Add '-9a' to each side of the equation.
5 + 2a + -9a = -16 + 9a + -9a

Combine like terms: 2a + -9a = -7a
5 + -7a = -16 + 9a + -9a

Answer 4

So...Combine like terms: 9a + -9a = 0
5 + -7a = -16 + 0
5 + -7a = -16

Answer 10
