Question

Subtract $16x-11y+2z$ from the sum of $7x+6y+z$ and $-9+3y-2z$

Answer 1

The given expressions are $16x-11y+2z,7x+6y+zand-9+3y-2z$

Let's perform the given operations:

Sum of $7x+6y+z$ and $-9+3y-2z$

$\Rightarrow 7x+6y+z-9+3y-2z=7x+9y-z-9$

Now, subtracting $16x-11y+2z$ from $7x+9y-z-9$

$\Rightarrow 7x+9y-z-9-(16x-11y+2z)$

$\Rightarrow 7x+9y-z-9-16x+11y-2z$

$\Rightarrow -9x+20y-3z-9$

Hence, $-9x+20y-3z-9$ is the answer.
