1. **State the problem:** Solve the system of equations using the elimination method.
Given system:
$$4x + 3y = 6$$
$$-x - 3y = 3$$
2. **Add the two equations to eliminate $y$:**
$$ (4x + 3y) + (-x - 3y) = 6 + 3 $$
$$ 4x - x + 3y - 3y = 9 $$
$$ 3x = 9 $$
3. **Solve for $x$:**
$$ x = \frac{9}{3} $$
$$ x = 3 $$
4. **Substitute $x=3$ into one of the original equations to find $y$:**
Using $$4x + 3y = 6$$:
$$ 4(3) + 3y = 6 $$
$$ 12 + 3y = 6 $$
5. **Isolate $y$:**
$$ 3y = 6 - 12 $$
$$ 3y = -6 $$
$$ y = \frac{-6}{3} $$
$$ y = -2 $$
6. **Final solution:**
$$ (x, y) = (3, -2) $$
This means the solution to the system is the point where the two lines intersect, at $(3, -2)$.
