1. **State the problem:** Solve the system of equations using the equalization method.
Given:
$$y = 3x + 5$$
$$y = 2x + 2$$
2. **Formula and rule:** Equalization involves setting the expressions for $y$ equal to each other since both equal $y$.
3. **Set equal:**
$$3x + 5 = 2x + 2$$
4. **Solve for $x$:**
$$3x + 5 = 2x + 2$$
$$3x - 2x = 2 - 5$$
$$x = -3$$
5. **Substitute $x = -3$ into one of the original equations to find $y$:**
Using $$y = 3x + 5$$:
$$y = 3(-3) + 5 = -9 + 5 = -4$$
6. **Solution:**
$$x = -3, y = -4$$

1. **State the problem:** Solve the equation:
$$x = 4 - 2y$$
This is a single equation with two variables, so it cannot be solved uniquely without another equation.
---
**Final answers:**
For the system:
$$x = -3, y = -4$$
For the single equation:
No unique solution without additional information.
