Answer:

Carla : 5

Carla : 5Dannie:

Carla : 5Dannie:Carla : 5 - 1 = 4

Carla : 5Dannie:Carla : 5 - 1 = 4Dannie: x - 13 - 1 = x - 14

Carla : 5Dannie:Carla : 5 - 1 = 4Dannie: x - 13 - 1 = x - 14x - 1 = 2 (4 + x - 14)

Carla : 5Dannie:Carla : 5 - 1 = 4Dannie: x - 13 - 1 = x - 14x - 1 = 2 (4 + x - 14)Simplify and expand the right side of the above equation
