Solve the equation:
6x - 5 + 8x - (2x+3) = 3(3x - 8)

Solve the system:
5x - 2y = 23
-4x + 2y = -18

Each box of tennis balls contains 3 tennis balls, while each box of baseballs only contains 2 baseballs. A store sold 26 boxes total. If a total of 70 balls were sold, how many boxes of each were sold?
