Solve for z:
6 (5 z-1)-2 (z+5) = 5 (z+1)
-2 (z+5) = -10-2 z:
-10-2 z+6 (5 z-1) = 5 (z+1)
6 (5 z-1) = 30 z-6:
30 z-6-2 z-10 = 5 (z+1)
Grouping like terms, 30 z-2 z-10-6 = (30 z-2 z)+(-10-6):
(30 z-2 z)+(-10-6) = 5 (z+1)
30 z-2 z = 28 z:
28 z+(-10-6) = 5 (z+1)
-10-6 = -16: 28 z+-16 = 5 (z+1)
Answer: | z = 21/23
