xyz=wing {2,7,8} in box 9, eliminates 2 from r9c7
UR type 3 {7,9} r13c25, makes naked pair {2,3} with r8c2
eliminates any other 2's and 3's in column 2
finned x-wing on 8, r28c179; r3c9 <> 8
xy-wing {2,7,9} removes 9 from r3c5
swordfish on 2 rows 3,6,8
xy-wing {2,3,7} removes 7 from r7c2 and r1c3
w-wing {6,7} removes 6 from r5c8

edit was because I put the wrong grid up.

the second puzzle

'------------------'------------------'------------------'

(5)r3c7 = (5)r9c7 - (5)r9c5 = (5)r4c5 - (5)r4c89 = (5)r5c8; r3c8 <> 5
(7)r2c6 = (7-1)r2c5 = (1-5)r4c5 = (5)r5c6; r5c6 <> 7

My path uses many of the same steps.

I start with a sky on 8's.
A swordfish on 2s, the UR on 79, xy-wing 27-9, and end with a 37 W-wing that eliminates a key 7.

A fun multi-stepper. Smile
