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