It really helps if you posted a link to the directions you were following. What you have posted is incorrect. The second "free" in that command should be "none".

diskutil  eraseVolume  free  none  disk0s3

If that command succeeds without any errors, then you will need to use the following command to expand the APFS Container (disk0s2) into the unallocated (free space) area....note the last character in this command is the number zero:

diskutil  ap  resizeContainer  disk0s2  0

FYI, it may be necessary to boot into Recovery Mode in order to modify the boot drive....if you do, then make sure to confirm the device identifiers for your internal drive since they may be different (you should do this no matter what since they can change every time you boot). Use the following command to only list the internal drive(s) and partitions/Containers/volumes:

diskutil  list  internal

Before attempting to modify any partitions on the drive, you should make sure you have a good current backup just in case something goes wrong and the macOS partition/Container is damaged or deleted. Modifying partitions and drive layouts is always a risky procedure even when using the Disk Utility GUI app. The Terminal command line has no safety nets and even a simple typographical error can have devastating & unintended results.
