2x-5 2x
__________________
K L M
1. KM = 35 a) Given
2. KL = 2x-5 b) Given
3. LM = 2x c) Given
4. KL+LM =KM d) Given
5. 2x-5+2x=35 e) Substitution Property
6. 4x=40 f) Addition Property of Equality
7. X=10 g) Division Property
2(10) – 5 +2(10) = 35 Seems to be true!

You can put this solution on YOUR website!
KL+LM = KM is not given, but it's actually true because of the segment addition postulate.


Also, I would add on "of Equality" to "Division Property". Other than that, everything else looks correct.
