Question

Evaluate the following expression using the values given:
Find 2x − 3y − z if x = −2, y = 3, and z = −2
@pooja195

Answer 1

Okay. So we just need to plug in the variables into the equation.

Answer 2

The equation we have is \(2x − 3y − z\)

Answer 3

Plug in the given values
2(-2)-3(3)-z
2 x -2=?

Answer 4

We know \(x = -2\)

and

\(y = 3\)

and

\(z = -2\)

Answer 5

plug em in

Answer 6

So lets plug it in!

When we do, we should get:

\(2(-2) − 3(3) − (-2)\)

Answer 7

Now what is \(2 * (-2)\)?

Answer 8

-4

Answer 9

Right so now we have!

\(-4−3(3)−(−2)\)

Answer 10

Now what is \(-3*3\)?

Answer 11

-9

Answer 12

Right! So now we have

\(−4−9−(−2)\)

Answer 13

Now what is \(-4 - 9\)?

Answer 14

almost there

Answer 15

-13?

Answer 16

Right! So what is -13 + 2?

Answer 17

-11
