1. **State the problem:** Solve the system of linear equations by elimination. Given the system: $$3x + 4y = 5$$ 2. **Explain the elimination method:** The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other. 3. **Since only one equation is given, we cannot solve for both variables uniquely.** 4. **If there was a second equation, for example:** $$ax + by = c$$ we would multiply the equations to align coefficients and subtract or add to eliminate one variable. 5. **Summary:** To solve a system by elimination, you need at least two equations. Here, only one equation is provided, so the system cannot be solved uniquely. **Final answer:** The system cannot be solved by elimination with only one equation.
