1. **State the problem:**
Find values of A and B given the system:
$$3A - 2 = 2B$$
$$5A = 3B + 5$$
2. **Write the equations:**
Equation 1: $$3A - 2 = 2B$$
Equation 2: $$5A = 3B + 5$$
3. **Isolate variables:**
From Equation 1, solve for $$B$$:
$$3A - 2 = 2B \implies B = \frac{3A - 2}{2}$$
4. **Substitute into Equation 2:**
$$5A = 3\left(\frac{3A - 2}{2}\right) + 5$$
5. **Simplify the substitution:**
$$5A = \frac{9A - 6}{2} + 5$$
Multiply both sides by 2 to clear denominator:
$$2 \times 5A = 9A - 6 + 10$$
$$10A = 9A + 4$$
6. **Isolate A:**
$$10A - 9A = 4$$
$$A = 4$$
7. **Find B using A:**
$$B = \frac{3(4) - 2}{2} = \frac{12 - 2}{2} = \frac{10}{2} = 5$$
**Final answers:**
$$A = 4$$
$$B = 5$$
