5 raruraru e ōrite ana ki:
\left\{ \begin{array}{l}{ n - y = 400 }\\{ y = 150 }\end{array} \right.
Tohaina
Kua tāruatia ki te papatopenga
n-150=400
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
n=400+150
Me tāpiri te 150 ki ngā taha e rua.
n=550
Tāpirihia te 400 ki te 150, ka 550.
n=550 y=150
Kua oti te pūnaha te whakatau.
