Güven  = x 

Erdem = y 

Çağrı= z

                                               x+y = 85    güven erdem 

                                               y+z = 89   çağrı erdem

                                               x+z =88       güven çağrı

 

2x+2y+2z= 262   her iki tarafı ikiye bölerim  

 

x+y+z = 131        y+z= 89 olduğuna göre    

 

131-89 = 42                   güven=  42 kg
