Linear System 611De3
1. **State the problem:** Solve the system of linear equations:
$$2x + 3y = 13$$
$$x - 4y = -5$$
2. **Formula and method:** We can use substitution or elimination. Here, we'll use substitution.
3. **Isolate $x$ in the second equation:**
$$x = -5 + 4y$$
4. **Substitute $x$ into the first equation:**
$$2(-5 + 4y) + 3y = 13$$
5. **Simplify and solve for $y$:**
$$-10 + 8y + 3y = 13$$
$$11y - 10 = 13$$
$$11y = 23$$
$$y = \frac{23}{11}$$
6. **Substitute $y$ back to find $x$:**
$$x = -5 + 4 \times \frac{23}{11} = -5 + \frac{92}{11} = \frac{-55}{11} + \frac{92}{11} = \frac{37}{11}$$
7. **Final answer:**
$$x = \frac{37}{11}, \quad y = \frac{23}{11}$$
