$x = 6 \\ y = 9 \\ \implies16 - 2x + 9y \\ \implies \: 16 - 2(6) + 9(9) \\ \implies \: 16 - 12 + 81 \\ \implies \: 4 + 81 \\ \implies \: 85$

Answer 2

Answer:

85

Step-by-step explanation:

Given:

$x=6\\y=9$

To find:

$16-2x+9y$

Solution:

$16-2x+9y=16-2(6)+9(9)$

⇒ $16-2(6)+9(9)$

⇒ $16-12+81$

⇒ $4+81$

⇒ $85$

∴ $16-2x+9y=85$
