1. **State the problem:** Solve the system of equations:
$$y = -\frac{3}{2}x + 3$$
$$y = x + 8$$
Check the solution at the point $(2,16)$.
2. **Set the equations equal to each other** since both equal $y$:
$$-\frac{3}{2}x + 3 = x + 8$$
3. **Solve for $x$:**
Move all terms to one side:
$$-\frac{3}{2}x - x = 8 - 3$$
Simplify the right side:
$$-\frac{3}{2}x - x = 5$$
Rewrite $x$ as $\frac{2}{2}x$ to combine:
$$-\frac{3}{2}x - \frac{2}{2}x = 5$$
Combine like terms:
$$-\frac{3+2}{2}x = 5$$
$$-\frac{5}{2}x = 5$$
Divide both sides by $-\frac{5}{2}$:
$$x = \frac{5}{-\frac{5}{2}}$$
Show cancellation:
$$x = 5 \times \cancel{\frac{1}{-\frac{5}{2}}} = 5 \times -\frac{2}{5} = -2$$
4. **Find $y$ by substituting $x = -2$ into one of the original equations, e.g., $y = x + 8$:**
$$y = -2 + 8 = 6$$
5. **Solution to the system:**
$$(x,y) = (-2, 6)$$
6. **Check the given point $(2,16)$:**
Substitute $x=2$ into both equations:
For $y = -\frac{3}{2}x + 3$:
$$y = -\frac{3}{2} \times 2 + 3 = -3 + 3 = 0$$
For $y = x + 8$:
$$y = 2 + 8 = 10$$
Since $y$ values are not equal (0 vs 10), $(2,16)$ is **not** a solution to the system.
**Final answer:** The solution to the system is $(-2, 6)$, and the point $(2,16)$ is not a solution.
