evaluate x-y for the given replacement values
x=7 and y=-22
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.
To evaluate x-y for the given replacement values of x=7 and y=-22, simply substitute the values into the expression.
x - y = 7 - (-22)
= 7 + 22
= 29
Therefore, x-y = 29 when x=7 and y=-22.
To evaluate x - y for the given replacement values x = 7 and y = -22, you simply subtract y from x.
Substituting the replacement values into the expression, we have:
x - y = 7 - (-22)
To simplify the expression, we need to remember that subtracting a negative is the same as adding a positive. So, the expression becomes:
x - y = 7 + 22
Now, we can easily calculate the value:
x - y = 29
Therefore, when x = 7 and y = -22, x - y equals 29.
