z - [ 2000 : [ (10 -5) x20 ]} = 9680
z - { 2000 : [ 5 x 20] } = 9680
z - { 2000 : 100 } = 9680
z - 20 = 9680
z = 9680 + 20
z = 9700
z - { 2000 : [ 5 x 20] } = 9680
z - { 2000 : 100 } = 9680
z - 20 = 9680
z = 9680 + 20
z = 9700
Z-{2000:[(100:10-5)*20]}=9680
Z-{2000:[(10-5)*20]}=9680
Z-{2000:[5*20]}=9680
Z-{2000:100}=9680
Z-20=9680
Z=9680+20
Z=9700
Succes!
