Question

Gideon made two errors in the proof. Identify and correct the errors

Answer 1

Identify: Step 6 and step 7

Correction:

I think step 6 is just not necessary and should be removed.

And step 7 should be the transitive property of equality not the Substitution Property of Equality

Answer 2

Should there be more to this? I can't figure out what you're asking
