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