What is the value of –2|6x – y| when x = –3 and y = 4?
kenny6666 [7]

Answer:

-44

Step-by-step explanation:

We have the expression

-2|6x - y|

We need to find the value of the expression when x = -3 and y = 4

Then we must replace the variable with the number -3 and the variable y with the number 4

This is:

-2|6(-3) - (4)|

-2|-18 - 4|

-2|-22|

Remember that the absolute value always results in a positive number.

So

-2|-22| = -2(22)=-44

the answer is -44
