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
