A/C not blowing cold air

Attached is a picture of the manifold reading. The compressor clutch engages, but still the air is not cold. I put my hand on the low-pressure line and it is not cold. I replaced the receiver/drier and the expansion valve. I flushed the lines and the evaporator as well. After doing some searches online, several websites state if the low side is high and the high side is low, it's possible the compressor is bad. I need to know definitely before I go out and buy a compressor because the clutch engages after adding Freon in the system.
