Question

Find 2x − 3y − z if x = −2, y = 3, and z = −2 −11 11 −15 15

Answer 1

Answer:

-11

Step-by-step explanation:

$2x - 3y -z$

To evaluate the given expression we plug in the given values

x = −2, y = 3, and z = −2

$2x - 3y - z$

$2(-2) - 3(3) -(-2)$

positive times negative is negative, also negative and negative is positive

Remove the parenthesis by multiplying the numbers

$2(-2) - 3(3) -(-2)$

$-4 -9+2=-11$

Answer 2

−4−3×3+2−4−9+2−11
The answer is -11.
Hope this helps :)
