L = length of board piece

a = length of first piece

b = length of second ( shorter ) piece

a = 2 b - 3

L = 18 = a + b = 2 b - 3 + b = 3 b - 3

3 b - 3 = 18 Add 3 to both sides

3 b - 3 + 3 = 18 + 3

3 b = 21 Divide both sides by 3

3 b / 3 = 21 / 3

b = 7 ft

a = 2 b - 3

a = 2 * 7 - 3 = 14 - 3 = 11 ft
