Answer:

644

Step-by-step explanation:

[tex]-216 * x - y[/tex]

We know that:

x = -3

y = 4

We can find the value of our expression by substituting x and y with the values given above. For example, instead of y, we'll put 4:

[tex]-216*x - y\\-216*(-3) - 4\\[/tex]

Since -216 * -3 is equal to 648:

[tex]648-4[/tex]

[tex]644[/tex]

Answer: 644
