Question

3|y - 2| - |3x + 8| при x= -6, y = -5

Answer 1

3|-5 - 2| - |3 *(-6) + 8|= 3|-7 | - |- 18+8|=21- 10=11

Answer 2

To find the value of the expression 3|y - 2| - |3x + 8| when x = -6 and y = -5, you simply need to substitute these values into the expression and perform the calculations step by step.

Step 1: Substitute the given values: x = -6 y = -5

Step 2: Calculate the expression: 3|y - 2| - |3x + 8|

Replacing y and x in the expression: 3|-5 - 2| - |3(-6) + 8|

Now, perform the operations inside the absolute value bars: 3|-7| - |-18 + 8|

Calculate the absolute values: 3 * 7 - |-10|

Perform the subtraction inside the absolute value bar: 21 - 10

Finally, calculate the result: 21 - 10 = 11

So, the value of the expression 3|y - 2| - |3x + 8| when x = -6 and y = -5 is 11.
