Final answer:
To solve the differential equation x + 2x + 10x = e⁻¹, you can simplify the equation and isolate x to get x = e⁻¹/13.
Step-by-step explanation:
To solve the given differential equation x + 2x + 10x = e⁻¹, we can combine like terms to simplify the equation: 13x = e⁻¹. Next, we can divide both sides by 13 to isolate x: x = e⁻¹/13.
