Tohaina
Kua tāruatia ki te papatopenga
2b=7-4
Whakaarohia te whārite tuarua. Tangohia te 4 mai i ngā taha e rua.
2b=3
Tangohia te 4 i te 7, ka 3.
b=\frac{3}{2}
Whakawehea ngā taha e rua ki te 2.
7a+4\times \frac{3}{2}=1
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
7a+6=1
Whakareatia te 4 ki te \frac{3}{2}, ka 6.
7a=1-6
Tangohia te 6 mai i ngā taha e rua.
7a=-5
Tangohia te 6 i te 1, ka -5.
a=-\frac{5}{7}
Whakawehea ngā taha e rua ki te 7.
a=-\frac{5}{7} b=\frac{3}{2}
Kua oti te pūnaha te whakatau.
