To solve the equation, we first need to simplify both sides of the equation by distributing and combining like terms:

2x - 5 - (x - 1) = -5(-1 - x) - 5
2x - 5 - x + 1 = 5 + 5x - 5
x - 4 = 5 + 5x - 5
x - 4 = 5x

Next, we want to isolate the variable x on one side of the equation. Subtract x from both sides:

x - x - 4 = 5x - x
-4 = 4x

Finally, we need to solve for x by dividing by 4:

-4/4 = 4x/4
-1 = x

Therefore, the solution to the equation is x = -1.
