1. Start with the system of equations:

4x + 3y = 3

5x + 3y = 6

2. Subtract the first equation from the second to eliminate \( y \):

(5x + 3y) - (4x + 3y) = 6 - 3

Simplifying gives:

x = 3

3. Substitute \( x = 3 \) into the first equation:

4(3) + 3y = 3

12 + 3y = 3

4. Solve for \( y \):

3y = 3 - 12

3y = -9

y = -3

5. Therefore, the solution is:

x = 3, \, y = -3
