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

Substitution is the method of substituting the given values into the expression to find the desired value.

Answer: The value of the expression 2x − 3y − z is -9.

Go through the steps to find the ultimate value of the expression.

Explanation:

Given expression: 2x − 3y − z, with x = -2, y = 3, z = -2

We will simply use substitution of the given values into the expression terms and find the value of the expression.

Thus, substituting the values of x, y and z, we get:

2x − 3y − z

⇒ 2 × (-2) - [3 × (3)] - (-2)

= -4 - 9 + 4

= -9

Thus, the value of the expression 2x − 3y − z is -9.
