System Elimination E9C2B3
1. **State the problem:** Solve the system of equations using elimination:
$$\begin{cases} 2x + 3y = 8 \\ 5x + 6y = 17 \end{cases}$$
2. **Explain the elimination method:** The goal is to eliminate one variable by making the coefficients of that variable equal (or opposites) in both equations, then subtract or add the equations.
3. **Make coefficients of $y$ equal:** Multiply the first equation by 2 to match the coefficient of $y$ in the second equation:
$$2 \times (2x + 3y) = 2 \times 8 \Rightarrow 4x + 6y = 16$$
4. **Subtract the second equation from this new equation:**
$$ (4x + 6y) - (5x + 6y) = 16 - 17 $$
Simplify:
$$4x - 5x + 6y - 6y = -1$$
$$-x = -1$$
5. **Solve for $x$:**
$$x = 1$$
6. **Substitute $x=1$ into the first original equation:**
$$2(1) + 3y = 8$$
$$2 + 3y = 8$$
7. **Solve for $y$:**
$$3y = 8 - 2 = 6$$
$$y = 2$$
8. **Final answer:**
$$\boxed{(x, y) = (1, 2)}$$
This is the point where the two lines intersect, confirming the solution to the system.
