Step 1: Simplify the equation. Combine the like terms on the left side of the equation. $$2x - x + 5 = 0$$ $$(2-1)x + 5 = 0$$ $$x + 5 = 0$$ Step 2: Solve for $x$. Subtract 5 from both sides of the equation. $$x + 5 - 5 = 0 - 5$$ $$x = -5$$ Step 3: Express the answer to two decimal places. Since -5 is an integer, to express it to two decimal places, we write it as -5.00. $$x = -5.00$$ The solution to the equation is: $$\boxed{-5.00}$$
