To solve the equation, we can start by simplifying both sides:

On the left side, we have -x + 5.

On the right side, we have 3x + (-11), which can be simplified to 3x - 11.

So the equation becomes:

-x + 5 = 3x - 11

Next, we can combine like terms by adding x to both sides:

-x + x + 5 = 3x - x - 11

This simplifies to:

5 = 2x - 11

Next, we can add 11 to both sides:

5 + 11 = 2x - 11 + 11

This simplifies to:

16 = 2x

Finally, we can divide both sides by 2 to solve for x:

16/2 = 2x/2

This simplifies to:

8 = x

So the solution to the equation is x = 8.
