Question

Evaluate the following expression using the values given. Find 4x - y - 2z if x = -2, y = 3, and z = -2

Answer 1

Answer:

The value of the provide expression is -7.

Step-by-step explanation:

Consider the provided expression.

$4x - y - 2z$

We need to find the value of the expression, for x = -2, y = 3, and z = -2.

Substitute the respective values in the provided expression.

$4(-2) - 3 - 2(-2)$

$-8 - 3 +4$

$-11 +4$

$-7$

Hence, the value of the provide expression is -7.

Answer 2

To evaluate the given expression, we need the values of each variable and substitute these values to the expression. Then, go on with the operations involved.

4x - y - 2z
4(-2) - (3) - 2(-2)
-8 - 3 + 4
-7
