Solution for u+1-2(-7u-5)=5(u-1) equation: 


Simplifying
u + 1 + -2(-7u + -5) = 5(u + -1)

Reorder the terms:
u + 1 + -2(-5 + -7u) = 5(u + -1)
u + 1 + (-5 * -2 + -7u * -2) = 5(u + -1)
u + 1 + (10 + 14u) = 5(u + -1)

Reorder the terms:
1 + 10 + u + 14u = 5(u + -1)

Combine like terms: 1 + 10 = 11
11 + u + 14u = 5(u + -1)

Combine like terms: u + 14u = 15u
11 + 15u = 5(u + -1)
