Evaluate the expression x=-5 when and y=2 .

x-7y

x-7y = -5 - 7(2) = -5 - 14 = -19

To evaluate the expression x - 7y when x = -5 and y = 2, substitute the values of x and y into the expression:

x - 7y = -5 - 7(2)

Now perform the multiplication and subtraction:

x - 7y = -5 - 14

Simplify further:

x - 7y = -19

Therefore, when x = -5 and y = 2, the expression x - 7y evaluates to -19.

To evaluate the expression x - 7y when x = -5 and y = 2, follow these steps:

Step 1: Replace x with -5 and y with 2 in the expression.
(-5) - 7(2)

Step 2: Multiply 7 and 2.
(-5) - 14

Step 3: Subtract 14 from -5.
-5 - 14 = -19

Therefore, when x = -5 and y = 2, the expression x - 7y evaluates to -19.
