First, simplify the left side of the equation by combining like terms inside the parentheses:

4x - 8 - 3 = 4x - 11

Now the equation is:

4x - 11 = 5

To solve for x, we want to isolate x on one side of the equation. We can do this by adding 11 to both sides:

4x - 11 + 11 = 5 + 11

Simplifying:

4x = 16

Finally, we can solve for x by dividing both sides by 4:

4x/4 = 16/4

Simplifying:

x = 4

Therefore, the solution to the equation (4x - 8) - 3 = 5 is x = 4.
