Question

| x + y | + x x = - 45 y = 72

Answer 1

|-45+72|+х=27+(-45)=-12

Answer 2

$| - 45 + 72| + ( - 45)$
$|27| - 45$
$27 - 45 = - 18$

Answer 3

To find the value of the expression |x + y| + x when x = -45 and y = 72, let's substitute these values into the expression:

|x + y| + x = |(-45) + 72| + (-45)

Now, calculate the values inside the absolute value and then the absolute value itself:

|-45 + 72| = |27| = 27

Now, the expression becomes:

27 + (-45)

Finally, perform the addition:

27 - 45 = -18

So, when x = -45 and y = 72, the value of the expression |x + y| + x is -18.
