If work is done by the system then your work value for the system would be negative because the system is losing energy due to work. If the work is done on the system, you work value for the system would be positive because the system is gaining energy.
If the system is doing work, it is losing energy, so it is negative. Think of it with yourself as the system, if you open a door you are transferring energy to the door, losing energy yourself (-).
If the system is doing work then it is losing energy so the value will be negative. If work is done on the system, it is gaining energy so it will be positive. similarly, if a system loses heat, it is negative. if it gains heat, it is positive.
