Kua tāruatia ki te papatopenga
0.75\times 0.4=0.4-x
Me whakarea ngā taha e rua ki te 0.4.
0.3=0.4-x
Whakareatia te 0.75 ki te 0.4, ka 0.3.
0.4-x=0.3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=0.3-0.4
Tangohia te 0.4 mai i ngā taha e rua.
-x=-0.1
Tangohia te 0.4 i te 0.3, ka -0.1.
x=0.1
Me whakarea ngā taha e rua ki te -1.
