Solve Graphical
1. **Stating the problem:**
We need to solve the system of linear equations using the graphical method:
$$\begin{cases} 3x - y = 4 \\ x = 4y - 17 \end{cases}$$
2. **Rewrite each equation in terms of $y$ (to graph):**
- From the first equation: $$3x - y = 4 \implies y = 3x - 4$$
- From the second equation: $$x = 4y - 17 \implies 4y = x + 17 \implies y = \frac{x + 17}{4} = \frac{1}{4}x + \frac{17}{4}$$
3. **Interpretation:**
- The first line has slope 3 and y-intercept -4.
- The second line has slope $\frac{1}{4}$ and y-intercept $\frac{17}{4} = 4.25$.
4. **Find the point of intersection algebraically (since graphical method looks at where lines meet):**
Set the two expressions for $y$ equal:
$$3x - 4 = \frac{1}{4}x + \frac{17}{4}$$
Multiply both sides by 4 to clear denominators:
$$4(3x - 4) = 4\left(\frac{1}{4}x + \frac{17}{4}\right) \implies 12x - 16 = x + 17$$
Bring terms together:
$$12x - x = 17 + 16 \implies 11x = 33 \implies x = 3$$
Find $y$:
$$y = 3(3) - 4 = 9 - 4 = 5$$
5. **Final solution:**
$$\boxed{(x,y) = (3,5)}$$
This is the point where the two lines intersect, solution of the system.
