Tohaina
Kua tāruatia ki te papatopenga
x=3\times 2
Whakaarohia te whārite tuatahi. Me whakarea ngā taha e rua ki te 2, te tau utu o \frac{1}{2}.
x=6
Whakareatia te 3 ki te 2, ka 6.
y+2\times 6=-6
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y+12=-6
Whakareatia te 2 ki te 6, ka 12.
y=-6-12
Tangohia te 12 mai i ngā taha e rua.
y=-18
Tangohia te 12 i te -6, ka -18.
x=6 y=-18
Kua oti te pūnaha te whakatau.
