Question

What does this add up to?

2x − 3y − z if x = −2, y = 3, and z = −2"

Answer 1

Substituting the values x = -2, y = 3, and z = -2 into the expression 2x - 3y - z gives 2(-2) - 3(3) - (-2), which simplifies to -4 - 9 + 2, resulting in -11.

Step-by-step explanation:

To solve for 2x − 3y − z with given values x = −2, y = 3, and z = −2, we substitute the values into the expression:

2(−2) − 3(3) − (−2) = −4 − 9 + 2 = −11.

The sum of the expression 2x − 3y − z is −11 when substituting the values for x, y, and z as provided.
