First, let's simplify the left side of the equation:

(2x+3) - 2(5x-1)
= 2x + 3 - 10x + 2
= -8x + 5

Now, let's simplify the right side of the equation:

(7x - 1) - 2(3 + 11)
= 7x - 1 - 2(14)
= 7x - 1 - 28
= 7x - 29

So, the equation simplifies to:

-8x + 5 = 7x - 29

To solve for x, we can move all the x terms to one side of the equation:

-8x - 7x = -29 - 5
-15x = -34

Now, we can solve for x by dividing by -15 on both sides:

x = -34 / -15
x = 34 / 15 or approximately x = 2.27

Therefore, the solution to the equation is x = 34/15 or approximately x = 2.27.
