Answer:
-12
Step-by-step explanation:
We start with the equation: ![xy-3x](https://tex.z-dn.net/?f=xy-3x)
Substitute the variables: ![(-4)(6)-3(-4)](https://tex.z-dn.net/?f=%28-4%29%286%29-3%28-4%29)
Solve using order of operations (start with multiplication): ![(-24)-(-12)](https://tex.z-dn.net/?f=%28-24%29-%28-12%29)
And then addition/subtration: ![(-24)-(-12)=-12](https://tex.z-dn.net/?f=%28-24%29-%28-12%29%3D-12)
