Answer 2

To evaluate the expression when x = -3 and y = -7, you simply substitute these values into the equation and solve for the result:

5|х + 9| - |3у - 4|

Step 1: Substitute x = -3 and y = -7 into the equation.

5|(-3) + 9| - |3(-7) - 4|

Step 2: Simplify the expression inside the absolute value signs.

5|6| - |-25|

Step 3: Calculate the absolute values.

5 * 6 - 25

Step 4: Perform the arithmetic operations.

30 - 25

Step 5: Finally, compute the result.

5

So, when x = -3 and y = -7, the value of the expression 5|х + 9| - |3у - 4| is 5.
