\[ x+7 y \text { for } x=-5 \text { and } y=-3 \] The expression evaluated at the given values is

Step 1 ：Given the expression \(x+7y\) for \(x=-5\) and \(y=-3\)

Step 2 ：Substitute the given values of x and y into the expression

Step 3 ：The expression becomes \(-5 + 7*(-3)\)

Step 4 ：Simplify the expression to get the result

Step 5 ：The result is \(-26\)

Step 6 ：Final Answer: \(\boxed{-26}\)
