evaluate x-y for the given replacement values

Question

x=7 and y=-22

Answer 1

To evaluate x-y, we substitute x=7 and y=-22 into the expression:

x-y = 7 - (-22)

Using the rule for subtracting a negative number, we can rewrite this as:

x-y = 7 + 22

Adding 7 and 22, we get:

x-y = 29

Therefore, x-y is equal to 29 when x=7 and y=-22.
