Question: 4x-3 divided by x+3 plus 1 equals 3x+1 divided x+3
1. **State the problem:** Solve the equation $$\frac{4x-3}{x+3} + 1 = \frac{3x+1}{x+3}$$. 2. **Rewrite the equation:** To work with a common denominator, express 1 as $$\frac{x+3}{x+3}$$: $$\frac{4x-3}{x+3} + \frac{x+3}{x+3} = \frac{3x+1}{x+3}$$ 3. **Combine the left side fractions:** $$\frac{4x-3 + x + 3}{x+3} = \frac{3x+1}{x+3}$$ Simplify numerator: $$\frac{(4x + x) + (-3 + 3)}{x+3} = \frac{5x}{x+3}$$ 4. **Rewrite the equation:** $$\frac{5x}{x+3} = \frac{3x+1}{x+3}$$ 5. **Since denominators are equal and not zero (note: $x \neq -3$), set numerators equal:** $$5x = 3x + 1$$ 6. **Solve for $x$:** $$5x - 3x = 1$$ $$2x = 1$$ $$x = \frac{1}{2}$$ 7. **Check for restrictions:** $x \neq -3$ to avoid division by zero, and $x=\frac{1}{2}$ is valid. **Final answer:** $$x = \frac{1}{2}$$
