1. **State the problem:** We are given two linear equations:
$$y = \frac{2}{3}x - 1$$
and
$$y = -x + 4$$
We need to find the point where these two lines intersect.
2. **Set the equations equal to find the intersection:**
Since both expressions equal $y$, set them equal to each other:
$$\frac{2}{3}x - 1 = -x + 4$$
3. **Solve for $x$:**
Add $x$ to both sides:
$$\frac{2}{3}x + x - 1 = 4$$
Rewrite $x$ as $\frac{3}{3}x$ to combine like terms:
$$\frac{2}{3}x + \frac{3}{3}x - 1 = 4$$
$$\left(\frac{2}{3} + \frac{3}{3}\right)x - 1 = 4$$
$$\frac{5}{3}x - 1 = 4$$
Add 1 to both sides:
$$\frac{5}{3}x = 5$$
4. **Isolate $x$ by dividing both sides by $\frac{5}{3}$:**
$$x = 5 \div \frac{5}{3}$$
Show cancellation:
$$x = 5 \times \cancel{\frac{3}{5}} = 3$$
5. **Find $y$ by substituting $x=3$ into one of the original equations:**
Using $y = -x + 4$:
$$y = -3 + 4 = 1$$
6. **Final answer:**
The lines intersect at the point
$$(3, 1)$$
