1. The problem is to solve the equation $\frac{2x+4}{x+2} = 3$ for $x$.
2. We start by stating the formula and rules: To solve a rational equation, multiply both sides by the denominator to eliminate the fraction, but remember to check for values that make the denominator zero.
3. Multiply both sides by $x+2$:
$$\cancel{\frac{2x+4}{x+2}} \times (x+2) = 3 \times (x+2)$$
which simplifies to:
$$2x + 4 = 3(x + 2)$$
4. Expand the right side:
$$2x + 4 = 3x + 6$$
5. Rearrange to isolate $x$ terms on one side:
$$2x + 4 - 3x = 6$$
$$\cancel{2x} + 4 - \cancel{3x} = 6$$
which simplifies to:
$$-x + 4 = 6$$
6. Subtract 4 from both sides:
$$-x + 4 - 4 = 6 - 4$$
$$-x = 2$$
7. Multiply both sides by $-1$ to solve for $x$:
$$x = -2$$
8. Check the denominator $x+2$ for $x = -2$:
$$-2 + 2 = 0$$
Since the denominator is zero, $x = -2$ is not allowed.
9. Therefore, the equation has no solution.
Final answer: No solution because $x = -2$ makes the denominator zero.
