Solve Rational Equation 31C6C8
1. The problem asks to solve the equation $$\frac{2x+3}{x-1} = 3$$ for $x$.
2. The formula used here is to eliminate the denominator by multiplying both sides of the equation by $(x-1)$, assuming $x \neq 1$ to avoid division by zero.
3. Multiply both sides by $(x-1)$:
$$\frac{2x+3}{x-1} \times (x-1) = 3 \times (x-1)$$
which simplifies to:
$$2x + 3 = 3(x - 1)$$
4. Expand the right side:
$$2x + 3 = 3x - 3$$
5. Rearrange terms to isolate $x$:
$$2x + 3 - 3x = -3$$
$$-x + 3 = -3$$
6. Subtract 3 from both sides:
$$-x = -6$$
7. Multiply both sides by $-1$:
$$x = 6$$
8. Check the solution by substituting $x=6$ back into the original equation:
$$\frac{2(6)+3}{6-1} = \frac{12+3}{5} = \frac{15}{5} = 3$$ which is true.
Therefore, the solution is $x = 6$.
