Evaluate the expression when x = -2 and y = -4

Question

-4x - 7y = ______

Answer 1

To evaluate the expression \(-4x - 7y\) when \(x = -2\) and \(y = -4\), we can substitute the values of \(x\) and \(y\) into the expression.

\[ -4(-2) - 7(-4) \]

Now, calculate each term:

1. \(-4(-2) = 8\)
2. \(-7(-4) = 28\)

Now add the two results together:

\[ 8 + 28 = 36 \]

So, the value of the expression when \(x = -2\) and \(y = -4\) is:

\[ \boxed{36} \]
