Answer 2

To evaluate the expression 4(y+1) - 3|x+5| when y = -2 and x = -7, you simply need to substitute these values into the expression and perform the calculations step by step.

Let's start with y = -2 and x = -7:

4(y + 1) - 3|x + 5|

Step 1: Substitute y = -2 and x = -7:

4(-2 + 1) - 3|-7 + 5|

Step 2: Perform the arithmetic inside the parentheses and absolute value:

4(-1) - 3|-2|

Step 3: Evaluate the absolute value:

4(-1) - 3(2)

Step 4: Perform the remaining multiplication:

-4 - 6

Step 5: Finally, perform the subtraction:

-10

So, the result of the expression 4(y+1) - 3|x+5| when y = -2 and x = -7 is -10.
