-11x − 30 + 6x = 0

Sure, let's solve the equation step by step:

1. Combine like terms on the left side of the equation.

   -11x + 6x - 30 = 0

   This simplifies to:

   -5x - 30 = 0

2. Next, add 30 to both sides of the equation to isolate the term with x on one side:

   -5x = 30

3. Finally, divide both sides by -5 to solve for x:

   x = 30 / -5

   So, x = -6.
